Which tile goes where?
The right tile depends on how wet the area gets, how much traffic it takes and how easy it must be to clean.
Double charge vitrified
600 × 600, 800 × 800 mmGood for: living rooms, bedrooms and offices; hard-wearing, the colour runs deep.
Watch: polished surface can be slippery when wet.
Glazed vitrified (GVT, PGVT)
600 × 1200 mm and upGood for: marble and wood looks in living areas; large slabs with few joints.
Watch: the print is on the surface, so chips show; lay on a level base.
Anti-skid matt
300 × 300, 400 × 400 mmGood for: bathrooms, balconies, kitchens and stairs.
Watch: textured tiles hold dirt; seal and clean regularly.
Ceramic wall tiles
300 × 450, 300 × 600 mmGood for: bathroom walls and kitchen dado; light and easy to cut.
Watch: not for floors; they crack under load.
Full body or heavy duty
600 × 600 mm, 12 mm and upGood for: parking, shops, ramps and outdoor paths.
Watch: heavier and costlier; needs a firm base.
Buy from one batch. Shade and size can differ between batches; check the batch number on every box before the fitter starts.

4Method
How the quantities are worked out
The same steps a tile dealer uses to prepare an order.
- Tile cost by box. You pay for full boxes, so tile cost = boxes × pieces per box × tile area × rate per sq.ft.
- Grout = (L + W) ÷ (L × W) × joint × depth × 1.6 kg per sq.m.
- Layout drawing. The first floor in your list is drawn to scale with cut tiles shaded.

6FAQ
Questions
How many tiles do I need for a room?
Divide the area by the area of one tile including the joint, then add wastage. A 15 × 12 ft room is 180 sq.ft.; a 600 × 600 mm tile is about 3.88 sq.ft., so about 47 tiles, or 50 with 7% wastage, which is 13 boxes of 4. The calculator does this for every floor, wall and skirting in your list.
How much wastage should I add for tiles?
About 5 to 7% for a straight pattern in a regular room, 10 to 12% for diagonal laying, and 15% for herringbone or rooms with many corners. Small bathrooms and large tiles in small rooms waste more because of cuts.
How many tiles are in a box?
It depends on the size and maker. Common Indian packs are about 4 tiles of 600 × 600 mm, 3 of 800 × 800 mm, 2 of 600 × 1200 mm and 8 of 300 × 450 mm. The calculator lets you change pieces per box for each size to match your dealer.
Tile adhesive or cement mortar?
Tile adhesive gives a thin, strong bed and suits vitrified and large tiles, walls and tiling over old tiles. A cement-sand mortar bed about 40 mm thick is traditional for floors and helps level an uneven base. The calculator works out either one.
How much grout do I need?
It depends on tile size, joint width and depth. Smaller tiles have more joints and need more grout. The calculator uses (length + width) ÷ (length × width) × joint width × depth × 1.6 to get kg per square metre.
How is skirting calculated?
Skirting is the running length of the walls × the skirting height, usually 3 to 4 inches. It is often cut from the same floor tiles, so choose the floor tile size for the skirting row.
What does tiling labour cost?
Tile fitters in India usually charge per sq.ft., with walls a little higher than floors. The calculator uses ₹30 per sq.ft. for floors and ₹35 for walls and skirting; change them to your local rates.
