Tile Grout Calculator

Estimate grout volume, pounds, and bags from tile size, joint dimensions, entered density, and mixing allowance.

Inputs

Area and tile

Range: 1–100,000 ft2

Range: 0.5–120 in

Range: 0.5–120 in

Used only for the grout-type recommendation. Glass and some natural stones restrict the grout that may be used; the quantity still depends on joint geometry and density.

Joint

Range: 0.03–1 in

Range: 0.06–1 in

Grout and allowance

Range: 60–160 lb/ft3

Dry bulk density from the product data sheet. Cementitious grout is commonly about 100 lb/ft3; confirm on the bag.

Range: 5–50 lb

Range: 0–30
