O que é o Backsplash Tile Calculator?

A kitchen or bathroom backsplash is one of the most visible tiling jobs in a home — and one of the most material-intensive per square metre because of all the cuts around outlets, windows, and appliances. This calculator accounts for those openings and adds a 10% waste factor so your material order comes out right the first time.

You may also find the Grout Calculator, Countertop Calculator, and Paint Coverage Calculator useful.

Quem usa esta calculadora?

This tool is used by homeowners tiling a kitchen or bathroom, tile setters quoting backsplash jobs, and interior designers specifying finishes.

Como usar the Backsplash Tile Calculator

  1. Insira Wall length.
  2. Insira Wall height.
  3. Insira Tile size.
  4. Insira Window/door openings.
  5. Clique em Calcular para ver os resultados instantaneamente.

Fórmula

The calculator uses the following formula:

Area = (Wall length × height) - window openings; Tiles = ceil(area ÷ tile_size² × 1.1); Boxes = ceil(tiles ÷ per_box)

Exemplo de cálculo

A 3.6 m kitchen backsplash that is 0.5 m high with one 0.3 × 0.3 m window opening and 15 cm × 15 cm tiles (12/box) needs 8 boxes with waste included.

Cálculo passo a passo

  1. Backsplash area: 3 m × 0.6 m = 1.8 m²
  2. 10 cm tile area: 0.10 × 0.10 = 0.01 m² per tile
  3. Tiles needed: ceil(1.8 ÷ 0.01 × 1.1) = 198 tiles
  4. Typical box = 25 tiles → 8 boxes

Erros comuns a evitar

  • Measuring tile size in centimetres but area in metres — must be consistent
  • Forgetting the grout gap when placing tiles (use actual coverage area)
  • Not adding 10% extra for cuts, especially on mosaic or herringbone patterns
Pro Tip: Start tiling from the centre of the visible wall and work outward — this ensures cut tiles are symmetrical on both sides and the full tiles are at eye level.

Perguntas frequentes

What size tiles work best for a backsplash?
Small mosaic tiles (5–7.5 cm) are classic and handle curves well. Medium subway tiles (7.5 × 15 cm) are very popular for kitchens. Large format tiles (30 cm+) create a modern look but require more precise walls and generate more cut waste.

How do I measure a backsplash with windows and outlets?
Measure the full wall area (length × height), then subtract each opening. This gives the net tile area. The calculator does this automatically with the 'window openings' field.

What grout joint width should I use for backsplash tiles?
2–3 mm joints are standard for subway tiles. Mosaic tiles on mesh backing have 2 mm joints pre-set. Larger tiles can use 3–5 mm joints. Rectified tiles can go as tight as 1 mm.

Do I need waterproof tile adhesive behind a kitchen backsplash?
A standard cement-based tile adhesive is fine for kitchen backsplashes since they are not continuously wet. Bathrooms and shower areas need waterproof membrane systems behind the tiles.

How long does a backsplash tile job take?
A standard kitchen backsplash (3–4 m) takes 1 day to tile and 24 hours for adhesive to cure, then another hour to grout. Total: 2 days from start to grouting, 3–4 days before use.
