The international court is 28 m by 15 m. The NBA and NCAA court is 94 ft by 50 ft, and the high school court is 84 ft by 50 ft. Each figure is measured from the inner edge of the boundary line, and that detail is where most site surveys go wrong.<\/p>\n<p>Published basketball court dimensions usually stop at the boundary line. They never tell you how much floor to pave, how high the ceiling has to be, or how many turf rolls to order. We work from the rule texts and carry the same numbers through to the paved area, because that is where a project budget is decided.<\/p>\n<h2 id=\"dimensions-by-level\">Official Court Sizes for Five Rule Sets<\/h2>\n<p>Comparing basketball court dimensions by level belongs in one table, because every rule set measures from its own edge. FIBA counts from the inner edge of the boundary line. The NCAA and NFHS rules count from the inside edges of the sidelines and end lines.<\/p>\n<p>The measurement logic is not unique to basketball. Our guide to <a href=\"https:\/\/www.relyirgrass.com\/football-field-dimensions-guide-standard-soccer-pitch-sizes\/\">football field dimensions<\/a> applies the same line-based sizing and run-off logic to pitch standards, worth reading before a survey brief goes out.<\/p>\n<table>\n<thead>\n<tr>\n<th>Measure<\/th>\n<th>FIBA<\/th>\n<th>NBA<\/th>\n<th>WNBA<\/th>\n<th>NCAA<\/th>\n<th>NFHS<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Court length<\/td>\n<td>28 m<\/td>\n<td>94 ft<\/td>\n<td>94 ft<\/td>\n<td>94 ft<\/td>\n<td>84 ft<\/td>\n<\/tr>\n<tr>\n<td>Court width<\/td>\n<td>15 m<\/td>\n<td>50 ft<\/td>\n<td>50 ft<\/td>\n<td>50 ft<\/td>\n<td>50 ft<\/td>\n<\/tr>\n<tr>\n<td>Three-point, top of arc<\/td>\n<td>6.75 m<\/td>\n<td>23 ft 9 in<\/td>\n<td>22 ft 1.75 in<\/td>\n<td>22 ft 1.75 in<\/td>\n<td>19 ft 9 in<\/td>\n<\/tr>\n<tr>\n<td>Three-point, corner<\/td>\n<td>6.60 m<\/td>\n<td>22 ft<\/td>\n<td>22 ft<\/td>\n<td>21 ft 7.875 in<\/td>\n<td>Not labelled<\/td>\n<\/tr>\n<tr>\n<td>Free-throw line<\/td>\n<td>5.80 m from endline<\/td>\n<td>15 ft from backboard<\/td>\n<td>15 ft from backboard<\/td>\n<td>15 ft from backboard<\/td>\n<td>15 ft from backboard<\/td>\n<\/tr>\n<tr>\n<td>Key width<\/td>\n<td>4.90 m<\/td>\n<td>16 ft<\/td>\n<td>16 ft<\/td>\n<td>12 ft<\/td>\n<td>12 ft<\/td>\n<\/tr>\n<tr>\n<td>Rim height<\/td>\n<td>10 ft (3.05 m)<\/td>\n<td>10 ft (3.05 m)<\/td>\n<td>10 ft (3.05 m)<\/td>\n<td>10 ft (3.05 m)<\/td>\n<td>10 ft (3.05 m)<\/td>\n<\/tr>\n<tr>\n<td>Playing area<\/td>\n<td>420 m\u00b2<\/td>\n<td>4,700 sq ft<\/td>\n<td>4,700 sq ft<\/td>\n<td>4,700 sq ft<\/td>\n<td>4,200 sq ft<\/td>\n<\/tr>\n<tr>\n<td>Length in yards<\/td>\n<td>30.6 yd<\/td>\n<td>31.3 yd<\/td>\n<td>31.3 yd<\/td>\n<td>31.3 yd<\/td>\n<td>28 yd<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Free-throw lines use different references: the FIBA figure starts at the endline, while the others at the backboard plane.

That one sentence carries the whole layout, and the playing area covers 420 square metres.<\/p>\n<h3>The court and the floor<\/h3>\n<p>Around the court, the rules add a boundary lane at least 2 m wide and free of obstructions. That pushes the minimum floor size to 32 m by 19 m, and the floor covers 608 square metres. That is 188 square metres more paving than the marked court, about 45 percent more.<\/p>\n<h3>Painted lines and circles<\/h3>\n<p>All court lines are 5 cm wide and drawn in white or another contrasting colour. The centre line extends 0.15 m beyond each sideline, the centre circle has a radius of 1.80 m, and the free-throw semi-circles match.<\/p>\n<p>The free-throw line has its furthest edge 5.80 m from the inner edge of the endline and runs 3.60 m long. The restricted area is drawn by lines whose outer edges sit 2.45 m from the mid-point of the endlines, making the painted key 4.90 m wide.<\/p>\n<h3>Three-point arc and no-charge area<\/h3>\n<p>The three-point area is an arc of radius 6.75 m, measured from the point on the court beneath the centre of the basket. It joins two parallel lines whose outer edge is 0.90 m inside each sideline.<\/p>\n<p>That point sits 1.575 m from the inner edge of the endline. The top of the arc therefore reaches 8.325 m from the baseline. The no-charge semi-circle under the basket has a radius of 1.30 m, with 0.375 m parallel lines ending 1.20 m from the endline.<\/p>\n<div class=\"wp-block-image\">\n<figure data-img-slot=\"slot2\"><img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot2.webp\" alt=\"Indoor sports hall with a wall-mounted basketball hoop, high windows and exposed roof trusses over a light court floor\" class=\"wp-image-6090\" width=\"1200\" height=\"800\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot2.webp 1200w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot2-300x200.webp 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot2-1024x683.webp 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot2-768x512.webp 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot2-18x12.webp 18w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>Indoor halls are measured from the finished floor: the court is standard, the hall around it is not.<\/figcaption><\/figure>\n<\/div>\n<h2 id=\"nba-court-dimensions\">NBA Court Dimensions: 94 Feet by 50 Feet<\/h2>\n<p>The <a href=\"https:\/\/official.nba.com\/rule-no-1-court-dimensions\/\" target=\"_blank\" rel=\"noopener\">NBA Rule No. 1 court dimensions page<\/a> carries the professional markings. The court is 94 ft by 50 ft, which is 28.65 m by 15.24 m and 4,700 sq ft of playing area.<\/p>\n<h3>Court size and how it is measured<\/h3>\n<p>As with FIBA, the American dimensions run to the inside edges of the lines. The length is the space between the inner faces of the end lines, and the width between the sidelines. The US national metrology institute publishes the same court as 15.2 m by 28.7 m.<\/p>\n<h3>Three-point geometry and the restricted area<\/h3>\n<p>The three-point field goal area has parallel lines 3 ft from the sidelines and an arc of 23 ft 9 in from the middle of the basket. That puts the corner lines 22 ft from the centre line. The restricted area is a half-circle 4 ft from the centre of the basket ring, drawn with a solid two-inch line.<\/p>\n<p>The free-throw line is 2 inches wide and sits 15 ft from the plane of the face of the backboard. Hash marks sit 28 ft from the baseline and extend 3 ft onto the court, with a second set 13 ft from the baseline by the free-throw circle.<\/p>\n<h3>Backboard, rim and how the hoop is carried<\/h3>\n<p>The backboard measures 6 ft horizontally by 3.5 ft vertically. The ring has an 18 in inside diameter, its upper edge 10 ft above the floor, and its nearest inside point 6 in from the backboard face.<\/p>\n<p>How the hoop is carried changes the building plan. A wall-mounted glass backboard hangs a bending moment on the wall structure. The framing behind it has to be checked, and many facilities schedule an annual inspection for heavy units. A free-standing system needs floor area and a sound base, which matters when the run-off space is tight.<\/p>\n<div class=\"wp-block-image\">\n<figure data-img-slot=\"slot3\"><img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot3.webp\" alt=\"Empty indoor sports hall with a polished wood floor, blue court lines, tiered seating and a barrel-vaulted roof\" class=\"wp-image-6091\" width=\"1200\" height=\"800\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot3.webp 1200w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot3-300x200.webp 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot3-1024x683.webp 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot3-768x512.webp 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/10\/basketball-court-dimensions-slot3-18x12.webp 18w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>School and community halls usually carry several line sets, so the basketball markings have to be agreed before the floor goes down.<\/figcaption><\/figure>\n<\/div>\n<h2 id=\"ncaa-high-school-dimensions\">NCAA and High School Basketball Court Dimensions<\/h2>\n<p>The <a target=\"_blank\" rel=\"noopener\" href=\"https:\/\/ncaaorg.s3.amazonaws.com\/championships\/sports\/basketball\/rules\/men\/PRMBB_RulesBook.pdf\">NCAA men&#8217;s basketball rules<\/a> give college play the same 94 ft by 50 ft court as the professional game. What changes is the three-point line, the key width and the run-off the rules ask for.<\/p>\n<h3>NCAA: 94 ft by 50 ft with an international three<\/h3>\n<p>The playing court has sidelines of 94 feet and end lines of 50 feet, measured from the inside edges of those lines. The three-point field-goal line sits 22 feet 1.75 inches from the centre of the basket to the outside edge, and 21 feet 7.875 inches in the corners. That is the international distance adopted in 2019-20.<\/p>\n<p>The free-throw lane is 12 ft wide measured to the outside of each lane boundary, and the free-throw line has its farthest edge 15 ft from the backboard plane. Lines are 2 inches wide.<\/p>\n<h3>High school: 84 ft by 50 ft<\/h3>\n<p>The <a href=\"https:\/\/assets.nfhs.org\/umbraco\/media\/7213108\/basketball-court-diagram.pdf\" target=\"_blank\" rel=\"noopener\">NFHS court diagram<\/a> sets an optimum court 84 ft long inside the end lines and 50 ft wide inside the sidelines. The three-point line is 19 ft 9 in to the outside edge, and all lines are 2 inches wide. The NFHS diagram puts the free-throw line 15 ft from the backboard and 18 ft 10 in from the endline.<\/p>\n<p>The same diagram dimensions the backboards at 72 inches wide for the rectangular model and 54 inches for the fan model. It also carries the clause that a court less than 74 ft long should be divided by two lines parallel to and 40 ft from the farther end line.<\/p>\n<h3>Space and ceiling guidance<\/h3>\n<p>NCAA rules ask for at least 3 ft of unobstructed space outside the sidelines, and prefer 10 ft. NFHS rules carry the same minimum and preference; if 3 ft cannot be provided, a broken 1-inch line is marked 3 ft inside the boundary.<\/p>\n<p>For overhead clearance, the NCAA rules recommend that the ceiling and anything hanging from it, other than the basket, be at least 25 ft above the playing court. The same section recommends wall padding to current ASTM standards on features players may contact, installed no more than 4 inches from the floor to 6 feet.<\/p>\n<div class=\"wp-block-image\">\n<figure data-img-slot=\"slot4\"><img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-volleyball-badminton-court-green-net-fence.jpg\" alt=\"School multi-purpose court with green artificial turf, painted boundary lines and net posts behind a fence\" class=\"wp-image-2771\" width=\"1120\" height=\"680\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-volleyball-badminton-court-green-net-fence.jpg 1120w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-volleyball-badminton-court-green-net-fence-300x182.jpg 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-volleyball-badminton-court-green-net-fence-1024x622.jpg 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-volleyball-badminton-court-green-net-fence-768x466.jpg 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-volleyball-badminton-court-green-net-fence-18x12.jpg 18w\" sizes=\"auto, (max-width: 1120px) 100vw, 1120px\" \/><figcaption>School courts are shorter, and the site around them is usually whatever space is left.<\/figcaption><\/figure>\n<\/div>\n<h2 id=\"half-court-3x3-dimensions\">Half Court and 3&#215;3 Basketball Court Dimensions<\/h2>\n<p>A half court keeps the full width and half the length, so its numbers fall out of the table above.

It carries one basket, a free-throw line at 5.80 m and a 2-point line at 6.75 m. The 15 m side runs parallel to the end line, as on a FIBA half court of 14 m by 15 m. The two templates differ in depth, not in axis.<\/p>\n<p>The <a target=\"_blank\" rel=\"noopener\" href=\"https:\/\/fiba3x3.basketball\/docs\/FIBA%203x3%20Basketball%20Rules%20-%20Full%20version%20-%20Yellow%20Version.pdf\">FIBA 3&#215;3 official rules<\/a> add a boundary area of 1 m at the endline, 1.5 m at the sidelines and 2 m behind the baseline.

FIBA surrounds the court with a boundary lane at least 2 m wide and free of obstructions. Any obstruction, including seated staff and substitutes, must be at least 2 m from the court.<\/p>\n<div class=\"callout callout-warning\">\n<p><strong>One citable ceiling figure only.<\/strong> NCAA rules recommend at least 25 ft above the playing court. The 2024 FIBA rules contain no ceiling clause, so the widely repeated 7 m minimum has no basis in the current rule text.<\/p>\n<\/div>\n<p>Clear height is a story about the shot, not the ceiling alone. The FIBA arc tops out 8.325 m from the baseline, so the strip of ceiling above the arc matters more than the strip above the basket. A soffit or beam that dips over the arc apex is the obstruction players notice. The wall behind each end line is set by run-off depth instead.<\/p>\n<p>Backboard supports follow from the same geometry. A ceiling-hung system needs a structure that carries the load, a wall-mounted unit a wall that takes the bending moment. Both need room outside the run-off.<\/p>\n<ul>\n<li>Decide the level first: FIBA, NBA, WNBA, NCAA or high school sets every other dimension.<\/li>\n<li>Measure from the inner edge of the boundary line, never from the outer edge.<\/li>\n<li>Add the run-off each rule set asks for, and check what else sits in that band.<\/li>\n<li>Confirm clear height and how the backboard will be supported before the floor is specified.<\/li>\n<li>Work out the paved area next, and only then the turf quantity.<\/li>\n<\/ul>\n<div class=\"wp-block-image\">\n<figure data-img-slot=\"slot6\"><img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-indoor-sports-field-facility-netting.jpg\" alt=\"Indoor sports arena with an artificial turf pitch, white and yellow yard lines, suspended netting and industrial floodlights\" class=\"wp-image-2500\" width=\"1120\" height=\"680\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-indoor-sports-field-facility-netting.jpg 1120w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-indoor-sports-field-facility-netting-300x182.jpg 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-indoor-sports-field-facility-netting-1024x622.jpg 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-indoor-sports-field-facility-netting-768x466.jpg 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-indoor-sports-field-facility-netting-18x12.jpg 18w\" sizes=\"auto, (max-width: 1120px) 100vw, 1120px\" \/><figcaption>Run-off space, ceiling netting and lighting sit outside the measured playing area, and they decide what the building has to hold.<\/figcaption><\/figure>\n<\/div>\n<h2 id=\"turf-area\">From Court Size to Turf Area Requirements<\/h2>\n<p>Turning basketball court dimensions into a paving area is a short calculation, and it decides the material order. Full-court playing areas run about 390-437 square metres: the high school court at about 390, the FIBA court at 420, and the NBA or NCAA court at about 437. The FIBA floor with its 2 m boundary lane is 608 square metres, and a 3&#215;3 court with boundary area is about 252.<\/p>\n<ul>\n<li>A 2 m by 25 m roll covers 50 square metres, suited to small courts and awkward shapes.<\/li>\n<li>A 4 m by 25 m roll covers 100 square metres and covers most paved layouts.<\/li>\n<li>A 5 m by 25 m roll covers 125 square metres and suits large areas with almost no seams.<\/li>\n<li>A 420 square metre FIBA court divides into five 4 m rolls by area alone, a 608 square metre floor into five 5 m rolls.<\/li>\n<li>Lay-out raises the count. A 25 m roll is shorter than the 28 m court, so four 4 m lanes need two pieces each: eight rolls. Three 5 m lanes cover the width in two pieces each, so six.<\/li>\n<li>An NBA or NCAA court of 4,700 square feet divides into five 4 m rolls, again before seam and edge allowance.<\/li>\n<\/ul>\n<p>The qualifier matters: seams, offcuts, run-off and line areas all consume material. A <a href=\"https:\/\/www.relyirgrass.com\/netball-court-turf-quantity\/\">netball court<\/a> carries the same problem, because its run-off adds area that the court lines alone never show.<\/p>\n<p>Our artificial grass rolls come in 2 m, 4 m and 5 m widths at 25 m long. Yarn colour, shape, density, pile height, backing and roll size are made to the brief. Roll width can follow the court layout, which cuts seams that eat budget and time.<\/p>\n<p>Our page on <a href=\"https:\/\/www.relyirgrass.com\/what-is-a-multi-sports-court\/\">what is a multi-sports court<\/a> shows how one surface serves several sports.

Indoors the surface must stay flat and predictable, walls close to play need padding, and lighting plus access routes decide whether the court works at night.<\/p>\n<ul>\n<li>Indoors: a hard, even surface, with padding on anything a player can reach.<\/li>\n<li>Indoors: lighting, entry points and spectator circulation planned with the court.<\/li>\n<li>Outdoors: drainage and a stable base take priority, because standing water ends the season.<\/li>\n<li>Dual use: ask for concentrated load and fluid resistance data before you sign.<\/li>\n<\/ul>\n<p>A multi-sport turf system compares the trade-offs directly, and it is the faster read if the surface is still open.<\/p>\n<p>Surface choice also drives the cost range of the project. The right comparison is the service life of the floor rather than the first invoice, so ask for wear data instead of a headline rate.<\/p>\n<h2 id=\"sizing-mistakes\">Common Basketball Court Sizing Mistakes to Avoid<\/h2>\n<p>In practice, basketball court dimensions are usually right and the measured edge is wrong. Each mistake below turns a correct number into a wrong site.<\/p>\n<h3>Measuring to the outer edge of the line<\/h3>\n<p>FIBA measures from the inner edge of the boundary line, and the NCAA rules from the inside edges of the sidelines and end lines. A tape on the outer edge of the paint adds the line width to every dimension.<\/p>\n<h3>Mixing FIBA and NBA numbers<\/h3>\n<p>A 28 m by 15 m international court and a 94 ft by 50 ft court are not the same layout. The free-throw line shows it: 5.80 m from the endline under FIBA rules, 15 ft from the backboard plane under NBA rules. Pick the level first, then stay in it.<\/p>\n<h3>Forgetting the run-off<\/h3>\n<p>The playing area is not the room. FIBA adds a 2 m boundary lane, and NCAA and NFHS ask for at least 3 ft outside the sidelines with 10 ft preferred. A court fitted without those bands will not take the officials that use them.<\/p>\n<h3>Treating the arc top as the corner distance<\/h3>\n<p>The arc top and the corner are different measurements in every rule set. The FIBA arc runs 6.75 m with corner lines 6.60 m from the centre line, and the NBA arc runs 23 ft 9 in with corners 22 ft. The NCAA quotes 21 ft 7.875 in.<\/p>\n<h3>Applying the wrong ceiling figure<\/h3>\n<p>The current FIBA rules contain no ceiling height, so a quoted 7 m minimum has no rule behind it. The only sourced figure is the NCAA recommendation of at least 25 ft above the playing court, and that is a recommendation.<\/p>\n<h3>Getting the 3&#215;3 depth wrong<\/h3>\n<p>A regular 3&#215;3 court is 15 m wide and 11 m deep, so its 15 m side runs parallel to the end line. A FIBA half court keeps that 15 m width and runs 14 m deep. Mixing the templates leaves the court 3 m short rather than turned sideways.<\/p>\n<h3>Ignoring the short court clause<\/h3>\n<p>A high school court can be shorter than 84 ft, and the NFHS rules set out how. A court less than 74 ft long should be divided by two lines, each parallel to and 40 ft from the farther end line. Designing to 84 ft without that clause yields a court that cannot be divided.<\/p>\n<h3>Ordering turf by area instead of by layout<\/h3>\n<p>Area division gives a floor, not an order. The 25 m roll is shorter than the 28 m court, so the lay-out takes eight rolls where the area sum suggested five. Draw the roll plan before the order, then add edge allowance.<\/p>\n<div class=\"wp-block-image\">\n<figure data-img-slot=\"slot7\"><img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-installer-measuring-turf-carpet-tape-measure.jpg\" alt=\"Installer kneeling on artificial grass while measuring the turf roll width with a yellow tape measure\" class=\"wp-image-2671\" width=\"1120\" height=\"680\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-installer-measuring-turf-carpet-tape-measure.jpg 1120w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-installer-measuring-turf-carpet-tape-measure-300x182.jpg 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-installer-measuring-turf-carpet-tape-measure-1024x622.jpg 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-installer-measuring-turf-carpet-tape-measure-768x466.jpg 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-installer-measuring-turf-carpet-tape-measure-18x12.jpg 18w\" sizes=\"auto, (max-width: 1120px) 100vw, 1120px\" \/><figcaption>Every sizing mistake starts here: measure the finished playing area, then check the product width against it.<\/figcaption><\/figure>\n<\/div>\n<p><!-- relyirgate:C1 --><\/p>\n<h2 id=\"faq\">Frequently Asked Questions<\/h2>\n<div class=\"faq-card\" style=\"background:#f9f9f9;border-left:4px solid #1a5c2e;border-radius:4px;padding:25px;margin-bottom:18px\">\n<h3 style=\"color:#1a5c2e;margin-top:0\">What are the standard basketball court dimensions?<\/h3>\n<p>A FIBA court is 28 m by 15 m.
