Estimate grout per square meter based on tile size, joint width, and tile thickness before you buy bags.
Grout coverage answer
Grout per square meter rises when tile gets smaller, joints get wider, or tile gets thicker. That is why grout should be estimated with the tile format, not as a flat number.
Editorial review
This page combines a scenario answer, packaging checkpoints, and a live Tile Calculator handoff so the estimate is useful before you open the full tool.

Page scope
For How Much Grout Per m2?, start with small tile at Higher grout use. More joints per square meter. This is the number to verify against the measured project before you rely on the order quantity.
Small tile: Higher grout use. Cross-check it against Wide joints so the page is not reduced to a single rounded number.
For How Much Grout Per m2?, start with wide joints at Higher grout use. Joint width changes consumption fast. This is the number to verify against the measured project before you rely on the order quantity.
Wide joints: Higher grout use. Cross-check it against Large tile so the page is not reduced to a single rounded number.
Example grout ranges by tile format
| Tile format | Joint width | Approximate grout per m2 |
|---|---|---|
| 30 x 30 cm | 3 mm | 0.35 to 0.50 kg |
| 60 x 30 cm | 3 mm | 0.20 to 0.35 kg |
| 60 x 60 cm | 3 mm | 0.15 to 0.25 kg |
| 120 x 60 cm | 2 to 3 mm | 0.10 to 0.18 kg |
Use the quick answer as a first-pass estimate, then stress-test the scenario with the assumptions that usually move the order for how much grout per m2?.
For this page, the useful audit trail is the link between Small tile (Higher grout use) and Wide joints (Higher grout use). If either value changes on site, rerun the estimate before ordering.
A stronger estimator page should answer what the fast scenario misses, not only send users away to the calculator.
A credible estimator page should show how the headline answer turns into packaging, ordering, or material checkpoints.
For How Much Grout Per m2?, treat Small tile and Wide joints as a pair: one defines the measured scope, while the other shows how that scope becomes a practical order.
Use these checks before ordering
| Checkpoint | This page shows | Why it matters |
|---|---|---|
| Small tile | Higher grout use | More joints per square meter. |
| Wide joints | Higher grout use | Joint width changes consumption fast. |
| Large tile | Lower grout use | Fewer joints in the same area. |
| Planning rule | Buy whole bags | Packaging still controls the order. |
The fast estimate is useful because it frames the order early, but it should not hide where the result becomes too coarse.
How Much Grout Per m2? should be treated as a planning note, not a blind shopping list. Walk through the measurements, the supplier package rules, and the waste assumption before you accept the number shown at the top of the page.
If any checkpoint below does not match the real job, open Tile Calculator and change that input first. That keeps the page useful on its own while still handing complex cases to the calculator.
