Blank Sudoku Grid Template
Print empty sudoku grids in any size, with optional candidate dots and a name line.
How to use the Sudoku Grid Template
- Choose a grid size: 4x4, 6x6, 9x9, 12x12, 16x16 or samurai.
- Choose how many grids to place on each page. The options change with the size: 1, 2, 4 or 6 for 4x4, 6x6 and 9x9; 1, 2 or 4 for 12x12; 1 or 2 for 16x16; and 1 for samurai.
- Choose the number of pages, from 1 to 10; every page repeats the same layout.
- Choose your paper, US Letter or A4.
- Tick Add small candidate dots in each cell if you want faint dots for pencil marks.
- Tick Add a Name / Date line if you want one printed on the sheet.
- Check the grid width and cell size in millimetres that the tool shows below the preview for your layout.
- Click Print / Save as PDF to open the browser print dialog, or click Download SVG to get one grid as a vector file for a worksheet or whiteboard.
The preview shows the first page exactly as it will print, so check it before you print. For large print, choose one grid per page: the grid then uses the full width of the paper inside the margins. The SVG download holds a single grid, so use the print option if you need several grids or pages.
What is a blank sudoku grid used for?
A blank sudoku grid is an empty puzzle board that you fill in by hand. People use one to copy a puzzle from a newspaper or book, so they can try different ideas without marking the original, or to build a new puzzle from scratch.
Teachers use blank grids for classroom worksheets, and anyone can use a single large grid for one puzzle when small print is hard to read. The grid follows the standard sudoku rules: each row, each column and each box must contain every number once. For a 9x9 grid, the numbers are 1 to 9, and the boxes are 3x3 squares marked with thick lines.
Can I print blank 16x16 or 6x6 grids?
Yes. You can print both sizes, and each one has its own box shape. A 6x6 grid uses the numbers 1 to 6, with boxes 3 cells wide and 2 cells high. A 16x16 grid uses the numbers 1 to 16, with boxes 4x4 cells.
Because the cells in a 16x16 grid are small, the tool allows only 1 or 2 grids per page. Choose 1 per page if you want the largest cells. A 6x6 grid can be printed 1, 2, 4 or 6 to a page, so it suits worksheets with several puzzles.
How do I make my own sudoku on a blank grid?
Write a few digits into a 9x9 grid so that no digit repeats in a row, column or box, then try to solve it yourself. The hard part is uniqueness: a fair puzzle has exactly one solution, and a hand-made grid often has several. Type your clues into the Make your own mode of the sudoku generator, which counts the solutions as you type and can suggest a clue, then copy the final clues onto the printed grid.
Which grid size should I print?
Print 9x9 for normal puzzles from books and newspapers, 4x4 or 6x6 for young children, 16x16 for giant puzzles, and the samurai layout for five-grid puzzles. With one grid per page the tool shows how large each cell will be, so you can check that there is room for pencil marks.
