How to set the first course of a basketweave tile floor, how much extra material to order, and how to keep cut tiles out of the main sightline.
Order 15% extra material for a basketweave floor — more than the 10% that covers a plain straight-lay grid — because every tile has to keep a 2:1 length-to-width ratio and cut modules can't be spun to fill an odd gap. Start the layout from chalk lines snapped through the room's center, build full weave modules toward the main sightline (entry or hallway), and push the inevitable cuts to the perimeter walls where they're least visible.
Basketweave only works with a tile cut to a 2:1 length-to-width ratio, laid in pairs that alternate direction so one pair reads horizontal and the next reads vertical. Each module — one pair rotated against the next — takes 4 tiles to complete the repeat, and that repeat has to stay intact as it crosses the floor. A straight-lay grid can absorb an odd-sized gap at a wall with a single cut square; basketweave can't, because breaking one tile out of a module without cutting its partner to match kills the woven illusion.
That's why the waste allowance runs higher than a plain grid. Order 10% over the measured area for a straight-lay floor, but plan on 15% for basketweave, and step up to 20% if the pattern is being run on a diagonal against the walls. The extra material covers whole modules lost to partial rows at the perimeter, plus the dye-lot and breakage buffer every tile job needs regardless of pattern.
Run the room dimensions through the /floor-tile-calculator before ordering — it applies the pattern-specific waste percentage automatically instead of defaulting to the generic 10% most people assume covers any layout.

tile waste calculator guideSnap chalk lines through the center of the room rather than starting tight against a wall. Basketweave modules are square-ish blocks, and starting from center lets you work outward symmetrically in both directions, which is the only way to guarantee the cut row is the same width on opposite sides of the room instead of a full module on one side and a sliver on the other.
Orient full, uncut modules toward the sightline that matters most — the doorway a person walks through, a hallway view, or the sightline from an adjoining open room. Push the compromised row of cut modules toward the least-visible perimeter: behind a door swing, under toe-kick cabinetry, or into a closet threshold.
Before snapping anything, dry-lay two or three full modules on the actual tile to confirm the real footprint. Manufacturing tolerance on rectangular tile can shift the module size slightly from the nominal dimension, and a small drift compounds fast across a room. While you're checking that, run the joint width through the /tile-spacing-calculator — basketweave amplifies any grout line drift because the eye reads the joints as part of the weave pattern, not just a gap between tiles, so a consistent 1/8 in. (0.125 in.) joint matters more here than on a plain grid.

First, never let a perimeter cut fall under 50% of the full module width — a border narrower than half a module reads as an obvious patch rather than an intentional edge. Second, never let any single cut piece drop below 2 in. of width regardless of the module math; anything thinner chips easily and draws the eye as a sliver.
Because the pattern alternates orientation in pairs, a cut at the wall has to be planned across the whole module, not tile by tile. Measure back from the far wall to find where a complete module lands, then shift the starting chalk line rather than trimming mid-module and leaving a mismatched partner tile. Previewing the module grid in /patterns before cutting anything shows exactly where that boundary falls for the room's actual dimensions, which is faster than working it out with a tape measure and a story pole on site.
Where a run genuinely won't resolve into full modules — around a fixed obstruction like a hearth or an island — treat that wall as the sacrifice wall and put the irregular cuts there deliberately, rather than letting the math force an awkward cut onto whichever wall happens to be visible from the front door.

preview the module gridA 120 sq ft floor at the 15% basketweave waste allowance adds 18 sq ft of extra material, bringing the total order to 138 sq ft. If the tile is boxed at 10 sq ft per box, that total divides out to 13.8 boxes, which rounds up to 14 boxes since partial boxes aren't sold.
Buy the full 14 boxes in one order from a single dye lot rather than topping up later — basketweave's alternating orientation makes any shade variation between lots more noticeable than it would be on a plain grid, since adjacent modules sit at 90 degrees to each other and catch light differently. Keep whatever tile is left over after the install; basketweave repairs almost always need a matched pair of tiles rather than a single piece, so a partial box in storage saves a full box purchase later.

Start from chalk lines snapped through the center of the room, not from a wall, then build outward with full modules facing the main sightline — a doorway or hallway view — and push cut modules to the least visible perimeter.
No — basketweave depends on a 2:1 length-to-width tile ratio so pairs of tiles form a square module when set at right angles to each other; a square tile has no long axis to alternate, so the weave effect disappears.
Keep any perimeter cut at least 2 in. wide and at least 50% of a full module's width, and shift the layout's starting line rather than trimming a single tile out of a matched pair mid-module.
