Print bleed and margin checker
Check whether a finished print with bleed fits the printable part of your measured paper.
Result and working notes
Use 100% print scaling for this record. The sketch is not life-size and must not be used as a cutting pattern. Check measurements against the real materials.
Print width including bleed: 21.6 cm
Bleed is extra artwork outside the trim line. Printer margins are separate unprintable edges. Enter centimetres throughout. This checks dimensions; it does not add bleed to an existing PDF or change your printer settings.

How the estimate is calculated
Add twice the bleed to the finished width and height, then compare both orientations with paper size minus twice the printer margin. A 21 × 29.7 cm print with 0.3 cm bleed needs 21.6 × 30.3 cm.
A4 is too small; A3 with 0.5 cm printer margins provides 28.7 × 41 cm and fits. Bleed is extra artwork outside the trim line. Printer margins are separate unprintable edges. Enter centimetres throughout.
This checks dimensions; it does not add bleed to an existing PDF or change your printer settings.
