The beam height inside an existing hall decides more about an indoor field than any catalogue page. We have quoted rolls for halls where the floor measured right but the light fittings hung too low. The layout went back to the drawing board, and the order slipped a season.
Indoor sports turf planning is the discipline of fitting a playing surface into a fixed box. Clearance sits above, zones run across the floor, doors ring the edge, light falls on the pile, and a base sits underneath. Settle those elements in the wrong order and the mistake gets built in, not bolted on.
Why Planning Decides the Indoor Field First
An artificial turf installation inherits every constraint the building carries, and none of the freedoms an outdoor pitch enjoys. There is no weather to escape from, but also no sky above and no spare margin around the edges. Every planning element competes for the same fixed volume.
The sequence matters more indoors than out. A facility design guide for indoor soccer puts the most expensive mistake at the very start: choosing the building footprint before deciding what format the venue is meant to support. Once the format is wrong, every specification downstream becomes harder to fix.
Write the sports list first, with weekly hours for each. Small-sided indoor soccer fields commonly run 35 to 45 metres in length. Full indoor soccer fields sit near 52 to 61 metres long and 24 to 27 metres wide, so the two formats do not fit the same shell.
That is where indoor sports turf planning earns its keep: the order of these decisions decides the roll order months later. The surface brief follows the sports list, which is why our sports artificial grass systems are specified from playing hours and sport type rather than from a price list.
Measure Ceiling Clearance Before the Field Is Drawn
Indoor sports turf planning lives or dies on this measurement, because clearance is the one number no roll width can fix later. Sport England guidance asks sports hall designers to accommodate a minimum of 7.5 m of clear height. That figure is driven by the sport with the tallest demands: badminton.
The published numbers vary by sport, and competitive levels push them higher. Badminton guidelines require 7,500 mm above the finished floor for club play and 9,000 mm at Premier and International level, while international volleyball asks for 12,500 mm.
Two measurement rules catch buyers out. Published clearances apply to finished spaces, measured after lighting, ducting and other overhead structures go in. Services belong at least 7.7 m above the finished floor, with steelwork for roof-mounted basketball goals at 8.0 m or higher.
Match the numbers against what each sport actually needs before the field is drawn. Netball and competitive badminton sit at 7.5 metres, and general PE needs 6.0 metres or more. New school halls built at 4.5 to 5.5 metres cannot host the taller demands properly.
| Sport | Published clearance guidance |
|---|---|
| Basketball | 7.0 m |
| Volleyball | 7.0 m (12.5 m international) |
| Futsal / indoor soccer | 7.0 m |
| Badminton | 7.5 m club, 9.0 m Premier and International |
| Indoor tennis | 9.0 m |
| General PE and movement classes | 6.0 m or more |
The surface takes a slice of the same airspace. Every artificial turf installation adds its build-up to the stack. Published indoor builds run from about 10 to 16 mm for training turf to 12 to 25 mm for commercial gym installations. That matters most in older halls where the beams were never meant for a thick build-up. Our guide to non-infill turf for indoor athletic fields covers that trade in detail.
Zone the Floor for Training, Competition and Buffer
Three zone types share one indoor floor: a competition strip, training lanes and a buffer that keeps them apart. Treating the buffer as leftover space is how sessions start colliding. Zone it deliberately, with the same weight given to the gaps as to the playing areas.
Run-off is the first buffered dimension. Recreational layouts allow at least 1 metre beyond each short end of the field and around 0.5 to 1 metre along the sides, and competition environments often need more.
