Area: 1 A6 = 2 × A7 (A6 is double the area). Scaling factor: √2 ≈ 1.4142 per side.
A7 is the classic tag and mini-notecard size — this tool helps you scale up to A6 for notepads, cards, and small stationery.
A6 = A7 × 0.5 · Scale factor = √2 ≈ 1.4142 per side2 A7 sheets combine to make 1 A6 sheet (or 1 A6 = 2 A7).
📏 What is A7 Paper Size?
A7 is a very 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 tags, mini-notecards, small labels, and tiny notebooks. It's commonly used for product tags, business card alternatives, and compact stationery. A7 is exactly half the size of A6, making it perfect for small-scale design and portable applications.
📄 What is A6 Paper Size?
A6 is a small paper size in the ISO 216 series. Its dimensions are 105 × 148 mm (4.1 × 5.8 inches), with an area of 0.015625 m². A6 is the go-to size for notecards, postcards, pocketbooks, and small stationery. It's widely used for invitations, greeting cards, compact notebooks, and personal correspondence. A6 is exactly double the area of A7, making it a natural step up for more detailed content.
🧮 The Math: How A7 Becomes A6
The ISO 216 series is based on the aspect ratio of √2:1. Each step up (A7 → A6) doubles the area. The side lengths increase by a factor of √2 ≈ 1.4142.
- Width: 74 mm × √2 ≈ 105 mm
- Height: 105 mm × √2 ≈ 148 mm
- Area: 0.0078125 m² × 2 = 0.015625 m²
Formula: 1 A6 = 2 × A7 (in area). So, if you have 2 A7 sheets, they can be combined to form 1 A6 sheet (or 1 A7 = 0.5 A6).
