Area: 1 A6 = 2 × A7 (A7 is half the area). Scaling factor: 1/√2 ≈ 0.7071 per side.
A7 is the classic tag, label, and mini notecard size — this tool helps you scale down from A6 for tags, labels, and small stationery.
A7 = A6 × 2 · Scale factor = 1/√2 ≈ 0.7071 per side1 A6 sheet splits into exactly 2 A7 sheets (or 1 A7 = 0.5 A6).
📏 What is A6 Paper Size?
A6 is a small paper size in the ISO 216 A-series. Its dimensions are 105 × 148 mm (4.1 × 5.8 inches), with an area of 0.015625 m². A6 is the classic size for notecards, postcards, pocketbooks, and small stationery. It's commonly used for invitations, greeting cards, and compact notebooks. A6 is exactly twice the size of A7, making it perfect for portable documents and personal correspondence that can be folded into smaller formats.
📄 What is A7 Paper Size?
A7 is a very small paper size in the ISO 216 series. Its dimensions are 74 × 105 mm (2.9 × 4.1 inches), with an area of 0.0078125 m². A7 is the go-to size for tags, labels, small notecards, mini booklets, and compact stationery. It's also popular for price tags, product labels, and small-format publications. A7 is exactly half the area of A6, making it a natural choice for compact, portable documents.
🧮 The Math: How A6 Becomes A7
The ISO 216 series is based on the aspect ratio of √2:1. Each step down (A6 → A7) halves the area. The side lengths decrease by a factor of 1/√2 ≈ 0.7071.
- Width: 105 mm × (1/√2) ≈ 74 mm
- Height: 148 mm × (1/√2) ≈ 105 mm
- Area: 0.015625 m² ÷ 2 = 0.0078125 m²
Formula: 1 A6 = 2 × A7 (in area). So, if you have 1 A6 sheet, you can print 2 A7 tags from it (or fold it in half to create an A7 booklet).

💡 Professional Tips for A6 to A7 Scaling
🎯 Resolution & Quality
When reducing from A6 to A7, if your original is 300 DPI, the resulting A7 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 A6 for sharp A7 prints.
📐 Text Size Considerations
When scaling down from A6 to A7, text will appear smaller. For tags and labels, ensure your font sizes are at least 8-10pt at A6 so they remain readable at A7 (approximately 5-7pt after scaling).
💰 Printing Efficiency
Printing 2 A7 pages from 1 A6 sheet can save paper and costs. Many printers support automatic scaling — check your printer settings for "scale to fit" options.
📂 Storage & Organization
A7 is ideal for filing in small organizers and wallets. Use this converter to plan your stationery production and document organization.
