Garage tiles, gym rubber and play mats: counting the floor

Garage, gym and playroom floors are sold as tiles, rolls or mats rather than boxes of flooring, and each format wastes differently. Here is how to count each one, and what each weighs.

Three floors that float

Interlocking garage tiles, rubber gym flooring and foam play mats have one thing in common: they are laid loose on the existing floor, without glue or fixings, and most can be lifted again. That makes them quick to install and forgiving of a slab that is not perfect. It also means they are counted differently from wood or vinyl. You count whole tiles across a grid, or lengths of a roll, and the cut pieces at the edges are often thrown away rather than reused.

Garage floor tiles

Interlocking garage tiles are usually 12 inches square, in polypropylene, either solid or vented (with openings that let water drain under them). Count them as a grid: tiles across the width, tiles along the depth, each rounded up. Then add edge pieces. A ramped edge along the door opening lets cars and bikes roll on, and ramped edges also finish any side that is open rather than against a wall.

tiles across = width ÷ tile size, rounded up tiles deep = depth ÷ tile size, rounded up tiles to buy = across × deep, plus about 3% spare ramp edges = ramped length ÷ tile size, rounded up, plus a corner at each turn

A two-car garage

20 × 20 ft, 12 inch tiles, ramped edge across a 16 ft door.

  • Grid: 20 × 20 = 400 tiles; with 3% spare, 412 tiles
  • Ramp edges: 16 ft ÷ 12 in = 16 pieces, plus 2 corners

A one-car garage of 12 × 22 ft is a 12 × 22 grid of 264 tiles, 272 with spare, and the same 16 edges if the door ramp runs the full width.

The garage floor tiles calculator has common garage sizes built in and counts the edges and corners. Leave about 1/4 inch at the walls: plastic tiles grow in a hot garage. A slab with active moisture, oil or deep cracks should be dealt with first, even under a floating floor.

Rubber gym flooring

Rubber for home gyms comes in three formats, and the right one depends on the room and the weights.

Format Size Usual thickness Best for
Rolls 4 ft wide, cut to length 6–12 mm whole rooms, few seams
Interlocking tiles 24 × 24 in 8–10 mm DIY, easy to replace one tile
Stall mats 4 × 6 ft 19 mm (3/4 in) heavy lifting areas, cheapest per sq ft

A 20 × 14 ft garage gym in three formats

  • Rolls, 8 mm: 14 ft ÷ 4 ft = 4 strips of 20.25 ft = 81 ft of roll, 324 sq ft, about 405 lb, offcut 44 sq ft
  • Tiles, 8 mm: 74 tiles, 296 sq ft, about 370 lb, offcut 16 sq ft
  • Stall mats, 3/4 in: 15 mats, 360 sq ft, about 1,080 lb, offcut 80 sq ft

The weight is worth knowing before you buy: a 4 × 6 ft stall mat weighs about 70 lb and takes two people to move, and a full roll can weigh several hundred pounds. Delivery to the room matters. The flooring weights reference compares every floor per square foot. The rubber gym flooring calculator counts each format with its weight, and the flooring weight calculator compares the load of any floor.

Recycled rubber smells for a few weeks. Unroll it outdoors or in a ventilated garage and let it relax flat for a day so it does not curl at the ends.

Foam play mats

Interlocking EVA foam mats are usually 24 inches square, about 1/2 inch thick, sold in packs with border strips that give a straight edge. They cover a play area, not necessarily a room, and their size is usually set by the furniture around them. Count whole mats; foam is easy to cut but cut mats lose their interlocking edge.

A 12 × 10 ft play area

  • Grid: 12 ft ÷ 2 ft = 6 mats by 10 ft ÷ 2 ft = 5 mats = 30 mats
  • Packs of 6: 5 packs
  • Borders: 22 strips for the outer edges, usually included with the packs

The foam play mats calculator rounds the area to whole mats and counts the borders.

Choosing between them

For a garage you park in, interlocking polypropylene tiles: they resist tyres, oil and road salt, and vented tiles drain melting snow. Rubber stains from hot tyres and is not meant for vehicles.

For a home gym, rubber: it absorbs dropped weights and protects the slab. Stall mats under a lifting platform, rolls or tiles for the rest of the room. Polypropylene tiles crack under dropped weights.

For a playroom, foam: soft, warm, light and cheap, but dented by furniture and not durable under shoes.

Adding the costs

Each is priced differently: garage tiles per tile or per pack, rubber per square foot or per mat, foam per pack. Convert each to a price per square foot covered, offcut included, to compare. The units guide covers the conversion, and the complete method covers measuring the space. For a roll format, the arithmetic of strips and offcuts is the same as for sheet vinyl, which the sheet vinyl guide explains.
