Subway Tile Sizes: 3 × 6 and Its Relatives, Thickness, Joints and Coverage

Subway tile is the 3 × 6 in glazed wall tile, twice as long as it is wide; Daltile’s Rittenhouse Square 3x6 measures 7.60 × 15.20 cm. Flat ones are 5/16 in thick and bevelled ones 3/8 in, and a carton of 100 flat pieces covers 12.50 sq ft, 8 to the square foot. The same lines come in 2 × 8, 4 × 12 and 4 × 16 in, and Equipe makes 7,5 × 15 cm. Daltile recommends a 1/16 in wall joint, the ANSI A108.02 minimum. The 33% offset cap only covers sides over 18 in, so a 3 × 6 may go in half-tile running bond, though Daltile caps its 2 × 8, 4 × 12 and 4 × 16 in at 33%.

Coverage per box is the maker’s printed figure: some makers count the nominal size, some the actual size, so take it from the box or the sheet.

Enough orderedEnough

40 sq ft plus 10% for cuts is 44 sq ft: 4 boxes of 12.5 sq ft (100 pieces each). Your 4 boxes cover it.

Daltile’s Rittenhouse Square 3x6, 100 pieces to 12.50 sq ft, is filled in for a 40 sq ft wall plus Ca’ Pietra’s 10% for cuts.

Joint wide enoughPasses

The joint must be at least three times the size spread (0.02 in × 3 = 0.06 in) and never under 1/16 in, so 1/16 in here. Your 1/16 in joint passes.

Daltile’s 1/16 in wall joint is filled in; with a 0.02 in size spread the three-times rule asks only 0.06 in, so the 1/16 in floor applies.

Floor flat enoughFlat enough

For tile with every edge under 15 in, the surface may vary by 1/4 in in 10 ft; your 1/8 in gap is within it.

With every edge under 15 in, the wall may vary 1/4 in in 10 ft; a 1/8 in gap is an example.

Questions

What size is subway tile?

3 × 6 in nominal: Daltile’s Rittenhouse Square 3x6 is 7.60 × 15.20 cm and American Olean’s 7.50 × 15.20 cm. The same family runs to 2 × 8, 4 × 12, 4 × 16 and 3 × 12 in, and Equipe sells 7,5 × 15 and 7,5 × 30 cm.

How thick is subway tile?

5/16 in for flat tile and 3/8 in for bevelled (Daltile, American Olean); Ca’ Pietra’s are 7 and 9 mm.

How many subway tiles in a square foot?

Eight 3 × 6 in tiles: Daltile’s carton of 100 covers 12.50 sq ft. A bevelled carton holds 80 for 10.40 sq ft.

What grout joint for subway tile?

1/16 in, which Daltile and American Olean recommend and ANSI A108.02 sets as the minimum, provided it is at least three times the size range of the tiles. Bevelled tile is grouted at the depth of the bevel.

Can subway tile be laid at a half offset?

Yes under ANSI A108.02, whose 33% cap applies only to sides over 18 in. Daltile still asks for no more than 33% on its 2 × 8, 4 × 12 and 4 × 16 in linear tile.

For makers and exporters of wall tile

Buyers ask for the nominal and actual size, the thickness and edge, flat or bevelled, the glaze and body, pieces and square feet or square metres per carton, carton weight and cartons per pallet, and the joint you recommend. Mark the real tile and its carton on your own photo in SizeMarker, as in the picture at the top, and send one product card for WhatsApp or WeChat.
