tile grout volume calculator online

Use tile grout volume estimate online for area m2, tile length mm, tile width mm, joint mm, joint depth mm. Material-planning geometry only. Supplied dimensions and productivity are scenarios; no structural capacity or building-code compliance is determined.

How to use it

Enter area m2. Set tile length mm, tile width mm, joint mm, joint depth mm. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
area m2Main input. Positive values. 20
tile length mmOption. Positive values. 300
tile width mmOption. Positive values. 300
joint mmOption. Positive values. 3
joint depth mmOption. Positive values. 8

Calculation method

grout_L = area_m2*joint_depth_mm*(1-tile_length_mm*tile_width_mm/((tile_length_mm+joint_mm)*(tile_width_mm+joint_mm))) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply tile grout volume estimate to the case below, keeping the displayed units and assumptions. Material-planning geometry only. Supplied dimensions and productivity are scenarios; no structural capacity or building-code compliance is determined.

Tile Grout Volume Estimate — worked case

Settings: tile length mm: 300; tile width mm: 300; joint mm: 3; joint depth mm: 8

Input:

20

Calculated result for these inputs:

Output:

{
  "grout_L": 3.152632094892649
}

Choose the right tool

Start with measured net dimensions, then enter supplier coverage, spacing and waste allowances. A material estimate does not determine load capacity, safe construction details or compliance with local building requirements.

Limitations and common mistakes

  • Material-planning geometry only. Supplied dimensions and productivity are scenarios; no structural capacity or building-code compliance is determined.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.

Frequently asked questions
