Should You Subtract Kitchen Cabinets from the Square Footage Before Ordering LVP?

Measure the kitchen wall-to-wall, the same footprint you'd use to carpet or tile the room, and feed that gross number into the order. Cabinets, the island, and appliances stay in the calculation even though the flooring underneath them will never be seen once they're set. This isn't a rounding convenience — it's how the waste math is built.

Take a 10x12 kitchen: 120 sq ft of gross floor area, with an L-shaped base run plus a small island eating up 28 sq ft of that footprint. That's 23% of the room hidden under cabinetry. Only about 92 sq ft of plank will ever show, but the order still gets built from the 120 sq ft figure, because the standard waste allowance — 10% for a straight lay, 15% for diagonal or herringbone patterns — is applied to gross square footage. That allowance already prices in the cuts around toe-kicks, appliance notches, and wall trim. Subtract the cabinet footprint before applying that percentage and the boxes ordered fall short of what the layout actually consumes.

Timing changes the math more than anything else. In new construction, floating LVP is typically run first and cabinets are set on top of it, toe-kick and all — the full footprint gets covered by plank whether or not it's visible, so it has to be ordered. In a remodel where cabinets are already fixed to the wall, the installer is only laying the visible perimeter around them, but most still price the job off the gross footage anyway, because the boxes saved by excluding a fixed 28 sq ft run rarely offset the risk of coming up short on a room that has irregular cuts around an island or peninsula.

Permanent, never-coming-out cabinetry is the one case where trimming the order to the visible area holds up: if the run is staying for the life of the floor and the budget is tight on a large kitchen, ordering to the exposed square footage instead of the gross footage can shave real cost off a big job. That decision should be made deliberately, not by accident, and it should be flagged to whoever installs the floor later so nobody assumes coverage that isn't there.

Appliances don't get this exception. Refrigerators, ranges, and dishwashers get pulled for repairs, replacements, and cleaning behind them, and slide-in ranges expose a strip of floor on three sides. Their footprint should never be subtracted from the order even in a permanent-cabinet scenario, because the flooring under and around them needs to look finished the day someone finally moves the fridge.

The most immediate failure is running out mid-install and needing a second order. LVP is produced in batches, and dye lots shift between production runs — a reorder weeks or months later isn't guaranteed to match the color, sheen, or even the exact plank texture of the first delivery, which shows up as a visible seam line where the two runs meet.

The second failure surfaces later: a bare subfloor gap under cabinetry that was never covered becomes a problem the moment those cabinets come out for a kitchen remodel, an appraisal walkthrough, or a water-damage repair. An incomplete subfloor under permanent-looking cabinetry reads as an unfinished install to anyone who later opens that space up, and it forces a patch job with mismatched material instead of a clean continuation of the existing floor.

The quieter failure is arithmetic. The 10% and 15% waste figures are calculated against gross room area on the assumption that the room includes obstacles like cabinet runs and appliance cutouts. Subtract the cabinet footprint first and then apply the waste percentage to what's left, and the waste allowance ends up covering a smaller number than it was designed for — the order comes in short even though every step felt conservative.

Start with the full room dimensions — length times width, wall to wall — and don't deduct the cabinet, island, or appliance footprint from that figure. That gross number is the input the waste factor is designed to work against.

Apply the waste factor that matches the layout: 10% for a standard straight lay, 15% for a diagonal or herringbone pattern where cut angles eat more material. Run that math through the /lvp-flooring-calculator, which takes the gross footage and pattern choice and returns a box count without any manual subtraction steps to get wrong.

On top of the waste-adjusted total, set aside the manufacturer-recommended 5% attic stock — extra planks from the same production run, kept sealed in their original box — so a future repair or appliance swap has a guaranteed color and lot match instead of a reorder gamble.
