Document Size Guide
Find the right size for your next print.
Compare familiar paper formats, check exact dimensions and prepare a document that matches your order. All sizes below are finished sizes unless stated otherwise.
A-series paper size chart
A4 is a useful reference point: A3 has twice its area, while A5 has half its area. Each step down the series halves the area of the preceding sheet, with dimensions rounded to whole millimetres.
| Size | Millimetres | Centimetres |
|---|---|---|
| A0 | 841 × 1189 | 84.1 × 118.9 |
| A1 | 594 × 841 | 59.4 × 84.1 |
| A2 | 420 × 594 | 42.0 × 59.4 |
| A3 | 297 × 420 | 29.7 × 42.0 |
| A4 | 210 × 297 | 21.0 × 29.7 |
| A5 | 148 × 210 | 14.8 × 21.0 |
| A6 | 105 × 148 | 10.5 × 14.8 |
| A7 | 74 × 105 | 7.4 × 10.5 |
| A8 | 52 × 74 | 5.2 × 7.4 |
| A9 | 37 × 52 | 3.7 × 5.2 |
| A10 | 26 × 37 | 2.6 × 3.7 |
B-series paper sizes
B-series sheets have the same general proportions as A-series sheets, but sit between their equivalent A sizes and the next larger A size. For example, B2 is 500 × 707mm, compared with A2 at 420 × 594mm.
| Size | Millimetres | Centimetres |
|---|---|---|
| B0 | 1000 × 1414 | 100.0 × 141.4 |
| B1 | 707 × 1000 | 70.7 × 100.0 |
| B2 | 500 × 707 | 50.0 × 70.7 |
| B3 | 353 × 500 | 35.3 × 50.0 |
| B4 | 250 × 353 | 25.0 × 35.3 |
| B5 | 176 × 250 | 17.6 × 25.0 |
| B6 | 125 × 176 | 12.5 × 17.6 |
These are standard reference dimensions, not a promise that every size is offered for every GD Print product. Always match the product’s stated size and template.
DL, business cards and square formats
DL leaflet: 99 × 210mm
A slim format often used for leaflets, menus and inserts. It is approximately one third of an A4 sheet.
Check the exact product dimensions: some slim formats are specified as 100 × 210mm rather than 99 × 210mm.
Typical UK business card: 85 × 55mm
A common finished business-card size. Square, folded and other card formats have different dimensions.
Use the template for your chosen card; the size here is a reference example.
Square sizes
A square document has equal width and height, for example 148 × 148mm or 210 × 210mm. These are examples of a shape and size, rather than A-series names. Check the available size on the actual product page.
Common envelope sizes
| Envelope | Size in mm | Typical insert |
|---|---|---|
| C4 | 229 × 324 | A4 sheet, unfolded |
| C5 | 162 × 229 | A5 sheet, or A4 folded in half |
| C6 | 114 × 162 | A6 sheet, or A4 folded into quarters |
| DL envelope | 110 × 220 | A4 sheet folded into thirds |
An envelope is larger than the paper it holds. A DL envelope at 110 × 220mm is different from a DL leaflet at 99 × 210mm. Thick booklets, multiple inserts and unusual folds may need extra space; check fit before ordering.
Portrait, landscape and folded size
210 × 297mm
297 × 210mm
Flat size
The complete sheet before folding. An A4 sheet measures 210 × 297mm, or 297 × 210mm in landscape orientation.
Finished folded size
The size once folded. An A4 sheet folded in half creates an A5 format, approximately 148 × 210mm. For a booklet, the stated size usually describes one finished page.
Finished size is not the same as artwork size.
Bleed extends the background beyond the finished edge so it can be trimmed cleanly. GD Print’s general paper-print guidance is 3mm bleed on every edge, with important text and logos at least 5mm inside the trim. Specialist products and finishing can require different allowances; your exact product template takes priority.
| Format | Finished size | With 3mm bleed each edge |
|---|---|---|
| A4 | 210 × 297mm | 216 × 303mm |
| A5 | 148 × 210mm | 154 × 216mm |
| A6 | 105 × 148mm | 111 × 154mm |
| DL leaflet example | 99 × 210mm | 105 × 216mm |
| Business card example | 85 × 55mm | 91 × 61mm |
Image resolution at final size
For photographs in close-viewed paper print, aim for 300 pixels per inch at the finished printed size. Enlarging a small image does not create original detail. Vector logos stay sharp when resized; large-format artwork needs job-specific checks.
Millimetres to pixels: mm ÷ 25.4 × ppi. As an example, A4 at 300 ppi is approximately 2480 × 3508 pixels before bleed. Supply a correctly sized print PDF rather than relying on pixel dimensions alone.
See our illustrated bleed guide, image quality advice and PDF export help.

Reference dimensions in millimetres. Diagrams are not life-size. Product sizes, templates and agreed job instructions take priority.
