Basketweave Tile Calculator

Pairs of rectangular tiles laid at right angles to the pair beside them, making a woven look. Budget about 15% waste rather than the usual 10% — the repeat is two tiles wide, so cutting at the perimeter interrupts the weave and often wastes both tiles in a pair.

Picking a pattern sets the recommended waste factor.

Basketweave tile needed, with waste

Square footage to order for a basketweave layout at 15% waste

Area	Plain sq ft	With 15% waste	Extra vs a straight grid
Backsplash (30 sq ft)	30 sq ft	35 sq ft	2 sq ft
Small bathroom (40 sq ft)	40 sq ft	46 sq ft	2 sq ft
Bathroom (80 sq ft)	80 sq ft	92 sq ft	4 sq ft
Kitchen (120 sq ft)	120 sq ft	138 sq ft	6 sq ft
Living room (180 sq ft)	180 sq ft	207 sq ft	8 sq ft

The last column is what the pattern costs you in extra material over a plain grid — usually a good deal less than people fear, and worth knowing before you rule the pattern out.

Where the waste comes from

The repeat is two tiles wide, so cutting at the perimeter interrupts the weave and often wastes both tiles in a pair.

Waste is not a safety margin you can shave. It is a count of tiles that physically cannot be used, and it is set by the geometry of the pattern against the shape of your room. A long narrow room has more perimeter per square foot than a square one and wastes more of any pattern; a room with a bay, an island or several doorways wastes more again.

Keep the offcuts until the job is signed off. On a patterned floor the leftover wedges from one wall are sometimes exactly what the opposite wall needs, and the difference between 15% and 20% waste is often just whether someone bothered to sort them.

Other layout patterns

Comparing layouts before you commit? The tile pattern calculator puts them side by side, and the waste calculator works the allowance from your room shape rather than from a rule of thumb.

How this calculator works

Work out the plain square footage of the area first, then apply the pattern's waste factor on top. For basketweave that is about 15%, against 10% for a straight grid.

The repeat is two tiles wide, so cutting at the perimeter interrupts the weave and often wastes both tiles in a pair.

The pattern only reads correctly if the pair's combined width equals the length of the tile it sits against — which means the joint width is part of the geometry, not a free choice. Two 2x4 tiles with a 1/8 inch joint between them are 4 1/8 inches, not 4.

Dry-lay a section before committing. Two square metres set out on the floor tells you more about how the pattern meets your walls than any calculation, and it is the cheapest possible time to discover that the room is out of square.

Frequently asked questions

How much waste should I allow for a basketweave layout?

About 15%, compared with 10% for a straight grid. The repeat is two tiles wide, so cutting at the perimeter interrupts the weave and often wastes both tiles in a pair. Order it all in one go: a second order weeks later can come from a different production lot, and on a patterned floor a shade difference between lots is far more visible than it would be on a plain one.

What tile suits a basketweave pattern?

Small rectangles, 1x2 and 2x4 mosaics, often on sheets. The pattern only reads correctly if the pair's combined width equals the length of the tile it sits against — which means the joint width is part of the geometry, not a free choice. Two 2x4 tiles with a 1/8 inch joint between them are 4 1/8 inches, not 4.

Is basketweave harder to install than a straight grid?

Yes, and the difficulty is in the setting out rather than the cutting. A straight grid forgives a small error because it accumulates along one axis; a pattern accumulates error in two directions at once and it becomes visible quickly. Snap chalk lines for the whole field before laying anything, and check back to them every few rows rather than trusting the spacers.

Does basketweave need more grout?

It depends on the tile rather than the pattern — grout follows the joint length per square foot, which is set by the tile size and joint width. What the pattern changes is how much tile you buy, not how much grout each square foot needs. Size the grout from the tile dimensions with the grout calculator.
