How to Print Letter or Legal Documents on A4

Synthetic preparation worksheet v1 — 25 October 2026. Not a physical sample, app screenshot, certification or fulfilled order.

Calculate the ideal fit before checking printer margins

A4 is 210 × 297 mm, Letter 215.9 × 279.4 mm, and Legal 215.9 × 355.6 mm. With matching portrait orientation and no printer margins, Letter fits at min(210/215.9, 297/279.4) = 97.27%; Legal fits at 83.52%. These are upper-bound full-sheet calculations, not promised driver settings.

At those ideal scales, a 10-point label becomes about 9.73 points on Letter and 8.35 points on Legal. A smaller printable area can shrink it further.

Compare two previews deliberately

Actual size means 100%: Letter is 5.9 mm wider than A4; Legal is also 58.6 mm taller. Content outside the printable area can be cropped. Fit preserves the whole page within the printable area but changes scale.

In Acrobat choose Print → Size and compare Fit with Actual size. Check signatures, barcodes and edge labels in the preview. Do not treat a screen preview as proof of physical measurement.
