` = "Whole Tiles Per Row"`

Enter a value for all fields

The Whole Tiles Per Row calculator computes the number of whole tiles needed per row based on the length of the row, the width of the tile and the thickness of the grout lines.

INSTRUCTIONS: Choose units and enter the following:

• (wL) Wall Length (horizontal dimension)
• (tW) Tile Width (horizontal dimension)
• (gL) Grout Line Thickness

Whole Tiles Per Row (n): The number of tiles is returned rounded up to the nearest whole number (integer)

The Math / Science

The Whole Tiles Per Row equation is used to estimate the number of whole tiles needed for each row.  The equation doubles the number of whole tiles needed per half and adding 1 for the middle tile.

When tiling a wall it is recommended to start in the middle and work your way out.  This approach typically results in partial tiles on both edges (see equation).

Ceramic Tile Calculators

• Number of Ceramic Tiles:  This calculator estimates the number of tile needed for an area based on the area dimensions and the size of the tile. This calculator also estimates the amount of Mastic and Thinset Mortar needed.
• Number of Ceramic Tiles for Area with Angled Bump-out and Number of Ceramic Tile for Area with Squared Bump-out: These calculators estimate the number of carpet tiles needed for an area or room with a bump-out (angled bump-out or squared bump-out) based on the area dimensions and the size of the tile. These calculator also estimates the amount of Mastic and Thinset Mortar needed.
• Mastic Needed for Ceramic Tile: This estimates the number of gallons of mastic needed to apply ceramic tile to an area.
• Premix Thinset Mortar Needed for Ceramic Tile: This estimates the number of gallons of premixed thinset mortar needed to apply ceramic tile to an area.
