Area: 1 B1 = 2 ร B2 (B1 is double the area). Scaling factor: โ2 โ 1.4142 per side.
B1 is a professional standard for posters and large-format printing โ this tool helps you scale up from B2.
B1 (area) = B2 ร 0.5 ยท Scale factor = โ2 โ 1.4142 per side1 B1 sheet has twice the area of 1 B2 sheet.
๐ What is B2 Paper Size?
B2 is a medium-large paper size in the ISO 216 B-series. Its dimensions are 500 ร 707 mm (19.7 ร 27.8 inches), with an area of 0.354 mยฒ. B2 is widely used for posters, book covers, and professional printing. It's also popular for art prints, exhibition materials, and large-format marketing displays. B2 is exactly half the area of B1, making it a common choice for book signatures and medium-format posters.
๐ What is B1 Paper Size?
B1 is a large paper size in the ISO 216 B-series. Its dimensions are 707 ร 1000 mm (27.8 ร 39.4 inches), with an area of 0.707 mยฒ. B1 is the go-to size for large posters, architectural drawings, professional presentations, and exhibition displays. It's also popular for art prints, banners, and large-format marketing materials. B1 is exactly double the area of B2, making it a natural step up for more impactful designs.
๐งฎ The Math: How B2 Becomes B1
The ISO 216 B-series is based on the geometric mean of the A-series sizes. Each step up (B2 โ B1) doubles the area. The side lengths increase by a factor of โ2 โ 1.4142.
- Width: 500 mm ร โ2 โ 707 mm
- Height: 707 mm ร โ2 โ 1000 mm
- Area: 0.354 mยฒ ร 2 = 0.707 mยฒ
Formula: 1 B1 = 2 ร B2 (in area). So, if you have 2 B2 sheets, they can be combined to form 1 B1 sheet (or 1 B2 = 0.5 B1).

๐ก Professional Tips for B2 to B1 Scaling
๐ฏ Resolution & Quality
When scaling from B2 to B1, if your original is 300 DPI, the resulting B1 will be ~212 DPI โ still acceptable for most printing. For high-quality prints, design at 600 DPI at B2 to get ~424 DPI at B1.
๐ BโSeries vs. AโSeries
B-series sizes are larger than A-series sizes at the same number. For example, B2 (500 ร 707 mm) is larger than A2 (420 ร 594 mm). Use B-series when you need more space than A-series offers.
๐ฐ Printing Efficiency
Printing 2 B2 pages from 1 B1 sheet can save paper and costs. Many professional printers support B-series paper sizes โ check your printer settings.
๐ Book Production
B2 is a common size for book signatures. When planning a book, understanding how B2 converts to B1 helps with cover design and production planning.
