A4 or A3: which paper size does your document need?

Compare A4, A3 and A5, choose a size for text or diagrams, and avoid clipped edges and unnecessary shrinking when you print.

A large sheet with a smaller sheet resting over half of it, beside a ruler and teal paper clip.

Start with A4 for an ordinary text document. Consider A3 when a wide table or diagram needs more room, rather than simply because the document has many pages. If the recipient specifies a size, follow that requirement first.

Compare the dimensions

Adobe’s A-series reference gives the standard dimensions. These are useful starting points for choosing a format:

Size Dimensions When to consider it
A4 210 × 297 mm Text reports, CVs and study notes
A3 297 × 420 mm Wide tables and diagrams needing more space
A5 148 × 210 mm A compact booklet designed for that size

An A3 sheet has the area of two A4 sheets. Selecting larger paper does not, by itself, guarantee larger text: the print scaling setting determines how the content uses that space.

Try orientation before changing the whole job

For a table that is slightly too wide, try landscape orientation in the original document and check the columns again. Splitting a large table into sensible sections may also work better than enlarging an entire report.

For a diagram that must be read as one complete view, compare previews at both sizes. Print the busiest page first and read its smallest label at the distance you will actually use it.

Understand why edges get clipped

The PDF page size, the loaded paper and the printer’s printable area are different things. Adobe’s scaling guide explains that fitting adjusts the page to the printable area, while actual size preserves scale and can crop content that does not fit.

For dimensioned drawings, confirm the required scale and measure a sample before printing the set. For ordinary documents, use the final-file checklist so a layout problem does not get mistaken for a paper-size problem.

Check which sizes the shop offers

Warqti’s current size options are A4 and A3, with availability depending on the shop and printer. A5 appears here as a comparison, not as an in-app order option. Ask the shop separately about cutting and finishing if you want a smaller booklet.
