Use the paper you actually have
In many countries, A4 is the standard. In the United States and Canada, Letter is more common. Matching the export size to the paper in your printer avoids accidental scaling and clipped margins.
If a teacher sends A4 files but the printer is loaded with Letter, check the print dialog carefully before pressing print.
When A4 helps
A4 can be useful when you want a little more vertical rhythm or when a script needs grouped rows with steady spacing. It is also the safer default for international sharing.
If you are building multilingual worksheets, standardizing on A4 simplifies distribution.
When Letter helps
Letter is convenient when the worksheet is being used primarily in North American homes or classrooms. It reduces friction because families can print without changing paper.
If your audience is mostly US-based, Letter may lower support issues even when the content itself is unchanged.
Check the print preview
Whatever size you choose, always check print preview before exporting at scale. Look for clipped themes, oversized text, or automatic fit-to-page behavior from the printer driver.
A worksheet that looks fine on screen can still lose spacing when the print dialog silently rescales it.
