How this calculator works
Multiply wall width × height for each identical wall, then subtract openings (a standard door is ~21 sq ft, a small window ~6 sq ft, a large window ~12 sq ft). We divide by the tile face area and add waste.
For walls, do not subtract tiny obstacles like outlets — the cut tile around them still consumes most of a tile. Only subtract openings bigger than about 2 sq ft.
Frequently asked questions
Should wall tile joints be 1/16 or 1/8 inch?
1/16 in suits rectified (precision-cut) tile; 1/8 in is the safe standard for ceramic subway and handmade-look tile where edges vary. Never go below 1/16 in on walls.
Can I use floor tile on a wall?
Yes — any floor tile can go on a wall. The reverse is not true: wall-only tile is too soft for floors. Check the box for a wall-only marking before buying for a floor.
How high should I tile a bathroom wall?
Common heights are 4 ft (wainscot), 6 ft (shower splash height), or full height. Full-height tile makes small bathrooms feel taller and costs roughly one extra row of labor.
