Flooring Calculator

Estimate flooring area, boxes, underlayment, and trim.

Measurement guide

Measure each rectangular section separately and subtract permanent areas that will not receive flooring.

Record each area separately, keep units consistent, and update the estimate with a final site measurement before ordering.

Assumptions and limitations

Box coverage controls purchasing; this does not optimize plank cuts, carpet roll direction, transitions, or stair material.

Prices, tax, and delivery are user-entered planning figures, not supplier quotations.

Worked example

A 12 × 10 ft room with 5 sq ft excluded leaves 115 sq ft. At 10% waste, 126.5 sq ft is needed; divide by the box coverage and round up.

Frequently asked questions

What waste allowance should I use?

Simple rectangles often start at 5–10%; complex patterns, many cuts, or fragile material justify more based on the installation plan.

Why is the purchase quantity rounded up?

Packages and whole pieces usually cannot be bought fractionally, so purchasing rounds up while the exact quantity remains visible.

Can I order directly from this result?

Not without verification. Re-measure, check the product label, batch and stock, and confirm with the supplier or a qualified professional.

What does the cost estimate include?

Material cost uses the rounded purchase quantity, then adds entered labor, delivery, and tax; unlisted accessories are excluded.
