Separate Drawer Liner Coverage from Cutting Waste — Free
Drawer liners look small until their areas are added. Compare the area inside your drawers with the sheet area you bought, without pretending that the remainder is reusable offcut.
The proof surface
Moving-truck volume checks three-dimensional packing. This measures flat drawer footprints and distinguishes arithmetic spare area from a feasible cutting layout.
Why the flat version breaks
Using cabinet dimensions
Outside dimensions include walls and runners that do not need liner.
Calling the remainder usable waste
Area alone cannot tell whether the leftover shapes fit another drawer.
Mixing centimetres and metres
A hundredfold length error becomes a ten-thousandfold area error.
How to work the lining area receipt
Measure the bottom rather than the outside cabinet front. Enter centimetres and exclude rails or dividers that the liner will not cover.
Multiply the liner width and length in metres outside the tool, or copy an area from the label. Use 2 for two square metres, not 20000 square centimetres.
Each footprint is width × depth ÷ 10000 square metres. The sample covers 0.32 square metres, leaving an arithmetic 1.68 of a 2-square-metre purchase before cutting losses.
The row that takes cumulative coverage over purchased area is flagged, as are later rows. Even an unflagged plan can fail if the roll is too narrow or offcuts have the wrong shape.
What the lining area receipt replaces
| Question | Before | Visible working |
|---|---|---|
| Using cabinet dimensions | Outside dimensions include walls and runners that do not need liner. | Record actual purchased area |
| Calling the remainder usable waste | Area alone cannot tell whether the leftover shapes fit another drawer. | Convert and accumulate coverage |
| Mixing centimetres and metres | A hundredfold length error becomes a ten-thousandfold area error. | Sketch the cuts before opening the roll |
A local arithmetic aid replaces hand calculation, not expert review. No paid AI service is needed.

FIRST-LOAD
Research prototype — checkout unavailable. Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Area accounting only, not a nesting or fit guarantee. Confirm material suitability, usable roll dimensions and safe cutting methods separately.
Data note: Everything runs in this browser tab on the lining area receipt: your drawer | internal width cm | internal depth cm stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Go deeper: the companion app files the same reading as a till receipt with a tear-off foot
The article demo above runs without limits. The companion app keeps a local history, exports the rows as CSV, prints the lining area receipt reading, and holds your drafts on this device — one complete free run; the proposed $4 one-time filing layer is not currently for sale.
The lining area receipt reading is complete for free. The optional $4 layer adds print, row CSV and the last five local reading summaries; it does not add hidden answers. Checkout is not configured yet; the article demo remains unlimited.

What this is built on
- Method: Each footprint is width × depth ÷ 10000 square metres. The sample covers 0.32 square metres, leaving an arithmetic 1.68 of a 2-square-metre purchase before cutting losses.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
Before: Outside dimensions include walls and runners that do not need liner. After: the lining area receipt shows the working beside each named row so the reader can change the assumption and inspect the consequence.
Optional AI formatting, not calculation
For this lining area receipt, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a lining area receipt. Return plain rows only: drawer | internal width cm | internal depth cm. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: drawer | internal width cm | internal depth cm. No AI response is executed as code.
