Calculate the Extra Area Around a Bleed Trim
Bleed surrounds all four edges, so adding it to only one width and height understates the artwork area. Inspect the expanded dimensions before building a print file.
1 · print piece | trim width mm | trim height mm

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.
Data note: Everything runs in this browser tab on the trim chase: your print piece | trim width mm | trim height mm stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Each dimension has two edges receiving the allowance. After: the trim chase shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Boundary and sources
Rectangular geometry only, not print-production approval. Confirm bleed, safe area, marks and file settings with the printer.
- Method: Expanded width is trim width plus twice the bleed; height follows the same rule. Subtract trim area from expanded area and divide by one hundred for square centimetres.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-27, 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.
Mechanism: competence-autonomy-loop
Optional AI formatting, not calculation
For this trim chase, 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 trim chase. Return plain rows only: print piece | trim width mm | trim height mm. 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: print piece | trim width mm | trim height mm. No AI response is executed as code.
