Area: 1 B0 = 2 × B1 (B0 is double the area). Scaling factor: √2 ≈ 1.4142 per side.
B0 is the largest B-series paper size — this tool helps you scale up from B1 for professional printing and display planning.
B0 = B1 × 0.5 · Scale factor = √2 ≈ 1.4142 per side2 B1 sheets combine to make 1 B0 sheet (or 1 B0 = 2 B1).
📏 What is B1 Paper Size?
B1 is the second largest size in the ISO 216 B-series. Its dimensions are 707 × 1000 mm (27.8 × 39.4 inches), with an area of 0.707 m². B1 is commonly used for large posters, banners, architectural drawings, and professional displays. It's also popular for art prints, exhibition materials, and large-format marketing displays. B1 is exactly half the area of B0, making it a practical size for large documents and displays.
📄 What is B0 Paper Size?
B0 is the largest size in the ISO 216 B-series. Its dimensions are 1000 × 1414 mm (39.4 × 55.7 inches), with an area of exactly 1.414 m² — making it the largest standard paper size in the B-series. B0 is the go-to size for massive banners, billboards, large-scale architectural plans, world maps, and high-impact marketing displays. It's also used for technical drawings, engineering plans, and poster exhibitions where maximum visibility is required. B0 is exactly double the area of B1.
🧮 The Math: How B1 Becomes B0
The ISO 216 B-series is based on the geometric mean of the A-series sizes. Each step up (B1 → B0) doubles the area. The side lengths increase by a factor of √2 ≈ 1.4142.
- Width: 707 mm × √2 ≈ 1000 mm
- Height: 1000 mm × √2 ≈ 1414 mm
- Area: 0.707 m² × 2 = 1.414 m²
Formula: 1 B0 = 2 × B1 (in area). So, if you have 2 B1 sheets, they can be combined to form 1 B0 sheet (or 1 B1 = 0.5 B0).

| 1 B1 | 0.5 B0 | 141.4% (enlarge) | Standard large poster |
| 2 B1 | 1 B0 | 200% (double width/height) | Full billboard |
| 4 B1 | 2 B0 | 282.8% | Two billboard panels |
| 5 B1 | 2.5 B0 | 316.2% | Large exhibition display |
| 10 B1 | 5 B0 | 447.2% | Major exhibition |
| 25 B1 | 12.5 B0 | 707.1% | Building wrap |
| 50 B1 | 25 B0 | 1000% | Massive display walls |
🖨️ Real‑World Examples: B1 to B0 in Action
- 🖼️ Large Format Printing: B1 posters are common for professional displays. When you need to produce a massive B0 banner or billboard, this converter tells you exactly how many B1 pages fit into a B0 layout.
- 🏗️ Architectural Plans: B1 is used for detailed building sections; B0 is used for site plans and master layouts. Switching between them is seamless with the √2 scaling.
- 📊 Exhibition Displays: B1 panels are standard for trade shows; B0 offers a more commanding presence for keynote presentations and main displays.
- 🎨 Art & Photography: Many artists work on B1, but for gallery exhibitions, B0 offers maximum visibility and impact.
- 📬 Marketing Materials: B1 posters can be designed, and then the same artwork can be scaled to B0 for billboards and large-format advertising.
💡 Professional Tips for B1 to B0 Scaling
🎯 Resolution & Quality
When scaling from B1 to B0, if your original is 300 DPI, the resulting B0 will be ~212 DPI — still acceptable for most large-format displays. For fine art, start with 600 DPI at B1 to get 424 DPI at B0.
📐 Vector vs. Raster
Vector graphics (logos, text, architectural lines) scale perfectly. Raster images (photos) require high‑resolution source files to avoid pixelation when enlarged to B0.
💰 Cost Planning
B0 prints typically cost 2‑4× more than B1 due to paper, ink, and handling. Plan your budget accordingly, especially for large print runs or multiple displays.
🖨️ Printer Compatibility
B0 requires specialized large‑format printers (plotter/wide format). Always check your printer's maximum paper size before sending files.
