A5 paper size in CM, inches, MM and pixels.

A5 dimensions: which numbers should you enter?

For a document editor, enter 148 mm wide and 210 mm high, or select its A5 preset. For landscape, swap the sides. The ISO 216 standard covers trimmed A-series paper sizes; Adobe’s A5 reference also lists the 148 × 210 mm dimensions.

Inches are rounded here; millimeters are the nominal specification. Paper manufacturing and trimming have tolerances, so a measured sheet may vary slightly. None of these dimensions includes a border, bleed or binding allowance.

A5 size in pixels, from 72 to 600 PPI

An A5 page does not have one fixed pixel count. Choose the print resolution first, then calculate the pixels. The following values use the nominal millimeter size and round each result to the nearest whole pixel.

For a detailed A5 photo or raster flyer, 300 PPI is a useful starting point: 1748 × 2480 pixels. Follow your printer’s specification if it differs. A 72- or 96-PPI file is much smaller, but those labels do not make it suitable for close-up print. Text and vector artwork in a PDF need not be flattened into this pixel grid.

Why 1748, not 1754 pixels wide?

The difference comes from the physical width used in the calculation. A5 is 148 mm wide; half of a 297 mm A4 sheet is 148.5 mm. At 300 PPI, those give different answers:

A5 width:     148 ÷ 25.4 × 300 = 1748.03 → 1748 px
Half-A4 width: 148.5 ÷ 25.4 × 300 = 1753.94 → 1754 px

This guide uses 148 mm consistently. Keep full precision until the final rounding step. If a print provider supplies a template with a different size, check whether it describes a folded panel, bleed or another production allowance before changing it.

PPI describes image pixels per printed inch; DPI describes printer dots and is also commonly used as the name of an image’s resolution tag. Adobe’s resizing explanation distinguishes changing resolution from resampling pixels.

Making A5 pages from an A4 sheet

Place A4 landscape and bring its left and right edges together. The fold divides the 297 mm side into two 148.5 mm panels; the other side stays 210 mm. That is the familiar half-A4 format, with the small rounding difference from nominal A5 noted above.

Two flyers or one booklet?

• Two separate flyers: arrange two A5 designs on an A4 sheet, check the printer’s margins, then cut. Two 148 mm widths use 296 mm, leaving only 1 mm across the sheet—not enough for generous gutters or separate full bleeds.
• A folded booklet: one sheet printed on both sides makes four pages. A simple 8-page booklet uses two sheets; 12 pages uses three. Include any blank pages in the total.

For a multi-page PDF, let the print software arrange booklet order. In Acrobat’s Booklet print mode, choose the appropriate paper and duplex options, then print and fold one test copy. Ordinary “two pages per sheet” is not the same as booklet page ordering.

A5 trim size, bleed and safe margins

Trim is the finished 148 × 210 mm page. Bleed is artwork extending beyond the cut. A safe margin keeps text and important details inside that cut. They solve different problems.

Three millimeters is an example, not a universal instruction. Adobe’s bleed guidance also says to verify requirements with the print provider. Ask separately about the safe margin and space needed near a binding. Use larger stock if a two-up layout needs bleed beyond what A4 can hold.

Prepare an image for an A5 page

1. Decide whether you need an image or a document.For a text-heavy booklet, set the document to A5 in a page-layout editor. SuperUtils’ image tools do not arrange PDF pages, add bleed or impose booklets.
2. Check the original pixel dimensions.Open the image in the Image Metadata Viewer. For a full-page raster image near 300 PPI, aim for enough detail to cover 1748 × 2480 px after any crop.
3. Choose a crop or keep a border.A camera photo may not match A5 proportions. Crop in a crop-capable editor first, or place the whole photo inside the page with margins. The SuperUtils resizer does not crop or add a page border.
4. Resize only if the workflow requires it.Use the Image Resizer with Lock aspect ratio enabled. If its calculated second dimension is substantially different from the table, fix the crop instead of unlocking the ratio. A one-pixel difference can be normal rounding.
5. Set the resolution tag last, if requested.For JPG or PNG, use the DPI Converter after resizing. Then verify A5, orientation and scaling in the print dialog; the tag alone does not control every printing app.

Do not shrink a good original merely to hit a table value unless the destination requires it. Likewise, enlarging a small file may satisfy a pixel requirement without making it sharper. Keep the original and check the printed result before producing a batch.

A5 versus A4, A6 and 5×7

A5 suits a page you want to hold in one hand, such as a program or small notebook. A photo album slot labeled 5×7 is not an A5 slot. If your task is a standard small photo print instead, see the 4×6 photo size guide for its dimensions and cropping behavior.
