A6 Paper Size: Small Cards, Dimensions and Printing
A6 is a small 105 × 148 mm sheet for notes and compact handouts. It is not the same size as a 4 × 6 inch photo, even though the two may look similar in a shop.
| Measurement | Portrait dimensions |
|---|---|
| Millimetres | 105 × 148 mm |
| Centimetres | 10.5 × 14.8 cm |
| Inches, calculated | 4.1339 × 5.8268 in |
| PDF points, calculated | 297.638 × 419.528 pt |
Check a four-card layout before cutting
Four A6 rectangles arranged two across and two down occupy 210 × 296 mm. That fits the nominal A4 outline, but it leaves no horizontal space for outer margins or cutting gutters. A home printer that cannot print to the edge will clip content there. Keep the card design well inside each panel or print on a larger supported sheet and trim.
What can change when you print
A 4 × 6 inch sheet is 101.6 × 152.4 mm. An A6 design is 3.4 mm wider and 4.4 mm shorter. Fit may add whitespace; Fill or a borderless mode may crop. Use a new document in the intended size if the frame or card stock has a fixed opening.
Set up one sample first
- Create or inspect the PDF at the intended millimetre dimensions. Landscape swaps width and height; it does not change the paper size.
- Load matching paper, choose the correct tray and paper type, then check the application and driver settings.
- Use Actual Size for measured layouts. Use Fit only when an intentional reduction or enlargement is acceptable.
- Print one sample and measure a known reference before printing or cutting the remaining copies.
Does this paper have a pixel size?
Paper has physical dimensions. At a chosen 300 pixels per inch, a raster image covering this portrait sheet would be approximately 1,240 × 1,748 pixels. That is a calculation at one chosen resolution, not a fixed property of A6 or a guarantee of print quality. Vector text and lines work differently.
Sources and method
- ISO 216:2007: the scope of the ISO A and B series. Nominal millimetre dimensions are used; rounded inch values do not redefine the sheet.
- NIST: SI units of length: the exact conversion of one inch to 25.4 millimetres. Inch and point values below are calculated from the stated nominal dimensions.
