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%.

Daltile’s Rittenhouse Square 3x6 is filled in. Enter your wall, carton, joint and how flat the wall is; each check follows a figure or rule on this page.
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.
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.
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.
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.
