About Packwise

Packwise is an independent, free utility focused on one task: flooring & tile pack calculator. It presents the formula and assumptions alongside the answer so that a result can be checked rather than taken on trust.

What it does

Turn room measurements into whole packs. Combine rooms, choose a cutting allowance, and see what rounding up adds to your order.

How calculations work

Calculations run on your device. Displayed quantities are rounded to at most two decimal places; whole-pack purchasing counts round upward. More precision is retained internally. Display rounding is not a guarantee about a supplier or device measurement tolerance.

What it does not establish

Material estimate only. Excludes labor, tax, delivery, underlay and installation checks.

The guides are original worked explanations of arithmetic and practical input choices. They are not reports of physical tests, endorsements by a provider, or professional assessments. Verify important purchasing assumptions with the relevant supplier.

Reproduce a result

Keep the selected units, every input, the formula and the downloaded text summary together. If a result differs from a provider quote, check the assumptions before comparing prices. A wrong divisor, pack coverage or resolution target can give mathematically consistent but unsuitable estimates.
