🧮 How to Calculate A5 Size in Pixels
The formula to convert A5 paper size (148 × 210 mm) to pixels is simple:
🔢 Conversion Formula
Width in pixels: Width (px) = 148 × (DPI ÷ 25.4)
Height in pixels: Height (px) = 210 × (DPI ÷ 25.4)
Total pixels (megapixels): MP = (Width × Height) ÷ 1,000,000
Example: At 300 DPI: Width = 148 × (300 ÷ 25.4) = 1,748 px | Height = 210 × (300 ÷ 25.4) = 2,480 px
The constant 25.4 is the number of millimeters in one inch, which converts mm to inches before multiplying by the DPI value.

📈 Common Misconceptions About Paper Sizes and Pixels
- Misconception: "A5 has a fixed pixel size" — Fact: Pixel size depends entirely on DPI/PPI. A5 is always 148 × 210 mm, but pixel dimensions vary with resolution.
- Misconception: "Higher DPI always means better quality" — Fact: While higher DPI provides more detail, it's not always necessary. The optimal DPI depends on viewing distance and print size.
- Misconception: "DPI and PPI are the same" — Fact: DPI (dots per inch) is used for printing, while PPI (pixels per inch) is used for digital displays.
- Misconception: "A5 is the same as 5×8 inches" — Fact: A5 is 5.83 × 8.27 inches, slightly larger than 5×8.
- Misconception: "A5 is only for notebooks" — Fact: A5 is also used for flyers, brochures, invitations, and digital displays.
📡 Pro Design Tip: A5 Print Preparation
When preparing files for A5 printing, follow these professional guidelines:
- Resolution: 300 DPI for high-quality prints (1,748 × 2,480 px)
- Bleed: Add 3-5 mm bleed around all edges (full bleed for professional printing)
- Color Mode: CMYK for print, RGB for digital display
- File Format: PDF/X-1a or TIFF for best print quality
- Sharpening: Apply moderate sharpening for print output
- Total File Size: At 300 DPI, file sizes typically range from 5-15 MB (uncompressed TIFF)
📊 Understanding Resolution: DPI vs PPI
While often used interchangeably, DPI and PPI have distinct meanings:
- DPI (Dots Per Inch): Used in printing. Refers to the number of ink dots a printer can place per inch. Higher DPI = more detail.
- PPI (Pixels Per Inch): Used in digital displays. Refers to the number of pixels per inch on a screen. Higher PPI = sharper image.
- In practice: For design work, DPI and PPI are often used synonymously. When preparing files for print, focus on DPI.
- Recommended: For print, use 300 DPI. For web, use 72-96 PPI.
