Check the Depth Needed for Sleeved Keepsakes
Archival sleeves add depth even when each drawing looks flat. Estimate boxes per collection while keeping separate collections separate, rather than treating all empty space as interchangeable.

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 archive spine: your collection | sleeve count | filled sleeve thickness mm stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Lids and wall thickness reduce useful depth. After: the archive spine shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Boundary and sources
Storage geometry only, not conservation advice. Ask an archivist about fragile or valuable items and appropriate materials.
- Method: Thirty-six sleeves at 1.5 mm occupy 54 mm and need one 80 mm box. The 90 mm program collection needs two, even if another collection leaves spare space.
- 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.

Optional AI formatting, not calculation
For this archive spine, 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 archive spine. Return plain rows only: collection | sleeve count | filled sleeve thickness 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: collection | sleeve count | filled sleeve thickness mm. No AI response is executed as code.
