Count Folded Sheets and Blank Pages for a Zine — Free
Round each edition to whole folded signatures, then count the sheets for the run. See the blank pages per copy before adding filler at the last minute.
The proof surface
Print break-even tools price a run. This handles binding geometry and blank-page allowance, not sales, ink cost or printer-specific imposition.
Why the flat version breaks
Treating pages as sheets
A folded duplex sheet has four page faces in this model.
Combining editions before rounding
Each edition must make complete signatures independently.
Ignoring a separate cover
Its stock and page treatment may differ from the interior.
How to work the signature quire
Include front matter and any cover printed as part of the signatures. A separately printed cover is outside this count and should be estimated separately.
Use a multiple of four approved for your binding method. Sixteen is illustrative; printer limits, paper thickness and creep can require a different choice.
Twenty-eight pages in sixteen-page signatures become thirty-two page faces, four of them blank. At four page faces per folded sheet, twenty-five copies require two hundred sheets.
Number a paper mock-up and confirm orientation before printing. This estimate gives quantities, not imposed page order, grain direction, duplex settings or spoilage allowance.
What the signature quire replaces
| Question | Before | Visible working |
|---|---|---|
| Treating pages as sheets | A folded duplex sheet has four page faces in this model. | Choose a signature size |
| Combining editions before rounding | Each edition must make complete signatures independently. | Round each edition up |
| Ignoring a separate cover | Its stock and page treatment may differ from the interior. | Make a folded dummy |
A local arithmetic aid replaces hand calculation, not expert review. No paid AI service is needed.

FIRST-LOAD
Input is processed locally. 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.
This is a quantity estimate, not an imposition file. Confirm folding, paper thickness and press setup with the printer and a physical dummy.
Data note: Everything runs in this browser tab on the signature quire: your edition | content pages | copies 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 stapled evidence packet
The article demo above runs without limits. The companion app keeps a local history, exports the rows as CSV, prints the signature quire reading, and holds your drafts on this device — one free run, then $ 4 one-time for the layer that keeps filing.
The signature quire 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: Twenty-eight pages in sixteen-page signatures become thirty-two page faces, four of them blank. At four page faces per folded sheet, twenty-five copies require two hundred sheets.
- 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.
Before: A folded duplex sheet has four page faces in this model. After: the signature quire 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 signature quire, 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 signature quire. Return plain rows only: edition | content pages | copies. 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: edition | content pages | copies. No AI response is executed as code.
