拼豆板计算器
迷你豆（2.6 mm）、标准豆（5 mm）和巨型豆（10 mm）的豆数与成品尺寸双向换算，并算出设计要用几块拼豆板、要买多少颗豆。免费，无需注册。
适用于 Perler、Hama、Artkal 以及任何间距相同的拼豆。
Pegboard Calculator
Patterns are sized in beads; a frame or a gift box is sized in centimeters. Enter whichever you have.
One pattern square = one bead = one peg. Pixel art imports at its exact pixel dimensions.
Midi (5 mm) is the default size everywhere — the cheapest beads and the widest color range. Maxi is also sold as Biggie.
The standard square pegboard is 29×29 pegs — about 14.5 cm of midi beads. Boards interlock, so a bigger design just spans several of them. Set your own number if your board differs.
Beads roll off the board, and a misfused section is worth redoing rather than living with.
One bead, one peg
Finished size = beads × bead pitch, because every bead sits on exactly one peg. Midi beads are 5 mm, so two beads per centimeter and 29 of them across a standard board. What bead size and board shape actually change about a project is covered in the bead sizes and pegboards guide, and the fusing itself in how to iron fuse beads.
Results
Spans 4 pegboards at 29×29 each. Interlock them and fuse section by section, or fuse the sections separately and join the seams on the second pass. Totals are whole-design numbers — the per-color counts live in the pattern's color key.
| Beads | Finished | Total | Boards |
|---|---|---|---|
| 29 × 29 | 14.5 × 14.5 cm | 841 | 1 |
| 40 × 40 | 20.0 × 20.0 cm | 1,600 | 4 |
| 58 × 58 (selected) | 29.0 × 29.0 cm | 3,364 | 4 |
| 64 × 64 | 32.0 × 32.0 cm | 4,096 | 9 |
| 87 × 87 | 43.5 × 43.5 cm | 7,569 | 9 |
| 100 × 100 | 50.0 × 50.0 cm | 10,000 | 16 |
| 116 × 116 | 58.0 × 58.0 cm | 13,456 | 16 |

计算器背后的算法：成品尺寸 = 豆数 × 豆子间距，因为每颗豆正好放在一根钉上。标准豆是 5 mm，每厘米两颗；迷你豆是 2.6 mm；巨型豆（也叫 Biggie）是 10 mm。拼豆板数量也是同样的除法，只不过是对板来算：每个方向上，图纸宽度 ÷ 板的宽度，再向上取整。
拼豆板的尺寸比新手想象的更重要。标准方形拼豆板是 29×29 钉，用标准豆约 14.5 cm，任何更大的作品都要在拼接起来的几块板上完成，并分块熨烫。这不是问题，所有大作品都是这样做的，但在开始一个宽 145 颗、要跨二十五块板的设计之前，最好心里有数。
不同的豆子尺寸和板的形状到底会给项目带来什么变化，详见拼豆尺寸和拼豆板指南（英文）；熨烫这一步本身见如何熨烫拼豆（英文）。要按这些尺寸设计，拼豆图纸生成器在真实的拼豆网格上工作，并统计每种颜色的豆数；照片转拼豆图纸可以按你在这里算出的尺寸精确转换图片。
