Easy large print sudoku
Twenty boards with 50, 46, 42, 40 or 38 starting numbers, four of each. All of them finish by scanning, with no pencil marks. Start at 50 clues for a short sitting and work down; each card says how many clues it starts with.
Medium large print sudoku
Six boards with 33 starting numbers and 48 squares to fill. They still solve by scanning alone, they just take longer. The step up from the 38 clue boards above.
Hard large print sudoku
Six boards with 26 starting numbers. Scanning runs out on every one, and the card says what it needs next: locked candidates or a pair. The 21.1 mm squares leave room to write candidates.
22 mm squares, one sudoku per page
Six boards on a 198 mm grid, the largest 9x9 squares on this site: two easy, two medium and two hard. The margins shrink to 6 mm to make room, so print at actual size.
High contrast sudoku for low vision
Six boards in pure black on white: no grey lines, thicker rules between every square and bold digits. Two each of easy, medium and hard, on the same 190 mm grid.
Two large print sudoku per page
Four sheets with two boards each at 13.8 mm a square: two sheets of easy boards and two of medium. Both answers are on the second page.
Large print sudoku packs with solutions
Three six page PDFs, one per level: four boards of that level, one to a page, then two pages with all four solutions. One download, four puzzles and their answers.
Drawn large, not enlarged
Each sheet is laid out for the page it prints on. The margins come in to 10 mm, the subtitle line is dropped, and the board grows to 190 mm across with squares of 21.1 mm, against 20 mm on the standard sudoku pages. The lines around the 3x3 boxes are heavier, so the blocks stay clear from arm's length, and the digits fill about half the height of a square. A photocopier enlargement would only make the paper bigger.
Easy, medium and hard in the same print
The print stays the same size on every level. Easy boards start with 38 to 50 numbers and finish by scanning rows, columns and boxes. Medium boards start with 33 and still need nothing beyond that, only more patience. Hard boards start with 26, and scanning is not enough: each one needs locked candidates or a pair, which the card names, so the large squares get used for pencil marks.
What is the best sudoku for low vision?
Look for three things: large squares, thick lines and pure black print. The high contrast sheets on this page have all three: 21.1 mm squares, no grey anywhere, and bold digits. If square size matters most, the 22 mm sheets use a board 198 mm across, close to the full width of an A4 page.
The other formats
The sheets with two boards use 13.8 mm squares, for when one page has to last longer. The packs put four boards of one level into a single six page PDF, one board to a page, with the answers on the last two pages.
Printing so the size survives
Print at 100 percent or actual size. Fit to page shrinks the sheet by a few percent and gives away the size you printed it for. The margins are 10 mm on most sheets and 6 mm on the 22 mm ones, so check the preview: the outer frame of the board should be complete on all four sides. Black ink on plain A4 is enough, and a soft pencil leaves marks that are easier to see than a hard one. Every board has one solution, printed at the end of its PDF.
The same levels in standard print are on easy sudoku, medium sudoku and hard sudoku. For a smaller grid with 25 mm squares, try the 6x6 sudoku collection.
