拼豆板計算機
迷你（2.6mm）、中型（5mm）和大型（10mm）拼豆的豆數與完成尺寸互相換算，並算出設計會用到幾塊拼豆板，以及要買多少顆豆。免費，免註冊。
適用 Perler、Hama、Artkal，以及任何相同間距的拼豆。
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 |

計算機背後的算法：完成尺寸 = 豆數 × 拼豆間距，因為每顆豆都剛好放在一根釘上。中型拼豆是 5mm（每公分 2 顆），迷你是 2.6mm，大型（也有品牌叫 Biggie）是 10mm。拼豆板數量也是同樣的除法，只是換成在板子上算：圖案寬度 ÷ 拼豆板寬度，無條件進位，兩個方向都算。
拼豆板的尺寸比新手想的還重要。標準方形拼豆板是 29 × 29 釘，中型拼豆約 14.5cm，更大的作品就得用互相拼接的板子組成，再分區熨燙。這不是問題，所有大型作品都是這樣做的；但在開始一個寬 145 顆、要用到 25 塊板的設計之前，最好先知道。
不同的拼豆尺寸和拼豆板形狀實際上會改變作品的哪些地方，拼豆尺寸與拼豆板指南（英文）有詳細說明；熨燙步驟請看如何熨燙拼豆（英文）。要以這些尺寸設計，拼豆圖案產生器使用真實的拼豆格線，並算出每個顏色的顆數；照片轉拼豆則能把圖片轉換成你在這裡算出的精確尺寸。
