Area: 1 A7 = 2 × A8 (A8 is half the area). Scaling factor: 1/√2 ≈ 0.7071 per side.
A7 and A8 are the smallest standard paper sizes — perfect for miniature notecards, tags, labels, and compact stationery.
A8 = A7 × 2 · Scale factor = 1/√2 ≈ 0.7071 per side1 A7 sheet splits into exactly 2 A8 sheets (or 1 A8 = 0.5 A7).
📏 What is A7 Paper Size?
A7 is a small paper size in the ISO 216 A-series. Its dimensions are 74 × 105 mm (2.9 × 4.1 inches), with an area of 0.0078125 m². A7 is the classic size for miniature notecards, invitation inserts, gift tags, and small labels. It's commonly used for personal correspondence, craft projects, and compact stationery. A7 is exactly double the area of A8, making it perfect for small-scale creative projects.
📄 What is A8 Paper Size?
A8 is the smallest standard paper size in the ISO 216 series. Its dimensions are 52 × 74 mm (2.0 × 2.9 inches), with an area of 0.00390625 m². A8 is the go-to size for miniature labels, price tags, small notepads, and compact business cards. It's also popular for memory game cards, craft projects, and ultra-portable stationery. A8 is exactly half the area of A7, making it the smallest practical paper size for print.
🧮 The Math: How A7 Becomes A8
The ISO 216 series is based on the aspect ratio of √2:1. Each step down (A7 → A8) halves the area. The side lengths decrease by a factor of 1/√2 ≈ 0.7071.
- Width: 74 mm × (1/√2) ≈ 52 mm
- Height: 105 mm × (1/√2) ≈ 74 mm
- Area: 0.0078125 m² ÷ 2 = 0.00390625 m²
Formula: 1 A7 = 2 × A8 (in area). So, if you have 1 A7 sheet, you can print 2 A8 pages from it (or fold it in half to create an A8 booklet).

💡 Professional Tips for A7 to A8 Scaling
🎯 Resolution & Quality
When reducing from A7 to A8, if your original is 300 DPI, the resulting A8 will be ~424 DPI — actually higher quality! This is because you're concentrating the same pixels into a smaller area. For best results, design at 300 DPI at A7 for sharp A8 prints.
📐 Text Size Considerations
When scaling down from A7 to A8, text will appear smaller. For tags and labels, ensure your font sizes are at least 8-10pt at A7 so they remain readable at A8 (approximately 5-7pt after scaling).
💰 Printing Efficiency
Printing 2 A8 pages from 1 A7 sheet can save paper and costs. Many printers support automatic scaling — check your printer settings for "scale to fit" options.
📂 Craft & Stationery Planning
A7 and A8 are popular craft sizes. Use this converter to plan your cutting and printing efficiently, minimizing waste and maximizing creativity.
