Tile Grout Calculator の使い方 — tile grout do I need?
Calculate grout volume, weight and bag quantity using tiled area, tile dimensions, joint width, joint depth, density and waste.
Grout volume depends on the combined joint length around each tile, multiplied by joint width and depth across the tiled area.
Calculate grout volume, weight and bag quantity using tiled area, tile dimensions, joint width, joint depth, density and waste. The linked Sellible tool keeps the fields, units and output together so the assumptions can be reviewed before the result is used.
- 1
Measure the net tiled area after exclusions.
- 2
Enter nominal tile length, width, joint width and filled depth.
- 3
Apply the product density and round the resulting packs up.
Example values and result
These values demonstrate the method; replace them with measurements, rates or file details that match the real task.
- Tiled area
- 20 m²
- Tile size
- 600 × 300 mm
- Joint
- 3 mm wide × 8 mm deep
- Waste allowance
- 10%
Narrow joints around large tiles use much less grout than wide, deep joints around mosaics. Enter the real product density and bag size for a purchasing estimate.
精度と実用上の注意
- Read the grout manufacturer coverage table.
- Allow for tile thickness and the adhesive bed.
- Use a higher allowance for textured tiles or inexperienced application.
Common mistakes
- Entering tile dimensions in centimetres when the field expects millimetres.
- Assuming every joint fills to the full tile thickness.
- Ignoring product pot life and colour batch consistency.
