Paper & writing
Trim and corner-squareness test
Use the supplied trim guides to compare opposing edges and diagonals. This checks the result of cutting a rectangle rather than front/back printer registration.
Paper & writing
Fold-alignment test
Compare a crease with the supplied center and mirrored marks. This is a single-sided fold-alignment check, distinct from the duplex trial sheet.

Fold-alignment test / LETTER
A good fit for your idea?
Do not print on both sides unless a different diagnostic explicitly instructs it.
Test the fold independently
Align the paper edges deliberately before creasing, then compare the marks through the folded paper. Repeat with a fresh sheet to separate a one-off hand-fold error from a consistent setup problem.
Inside this edition
A printing diagnostic, not a certified measuring instrument.
From file to finished page
- Choose the paper size loaded in your printer and open the matching PDF.
- Print at actual size and measure the 50 mm reference line before using physical measurements.
- Print one side only. Fold precisely along the central dashed line, aligning the top and bottom edges before creasing.
- Hold the folded paper to light and compare each mirrored pair of crosshair marks. Record any displacement rather than assuming the two sides align.
- Unfold and inspect the crease against the center line. A folding error and a scaling error are different problems; repeat with a fresh sheet to distinguish them.
Printing and use notes
Make one trial on ordinary paper before using special stock or preparing a batch. No physical test result is claimed.

KEEP THE IDEA GOING
A few more possibilities.
Paper & writing
Duplex alignment trial sheet
Compare front and back placement in a two-sided trial. Follow this sheet’s duplex procedure rather than applying a fold-only check to a printing-alignment problem.
Paper & writing
Metric and inch print-scale reference
Check a printed reference before using physical dimensions from a template. This page provides a comparison aid; it is not a certified ruler or calibration service.
