Large print Sudoku grid

A single empty 9×9 on an A4 sheet. The squares are about twenty-five millimetres — large print, not a booklet thumbnail.

One blank grid, about 25 mm a square — large print.

The grids

  • Grid 1

What large print changes on a Sudoku

It changes whether you can see the work. A six-up sheet is economical and a newspaper grid is smaller still, often under five millimetres a cell. At that size a candidate mark is a guess at your own handwriting. Large print spends the whole page on one grid so the digit, the corner marks and the 3×3 boxes are all readable without leaning in.

The audience for that is not only “older readers”, though they are the ones who search the phrase. Anyone copying a puzzle off a phone, anyone teaching the game, anyone working in a dim room — they all want the same physical fact: a cell big enough that a 2 and a 7 cannot be confused once the pencil has been over the page for an hour.

This is a blank grid, not a generated puzzle. Large-print editions elsewhere usually mean a booklet of already-filled clues at a bigger type size. The job here is the sheet itself: you bring the clues, we give you the paper they will actually fit on.

How big the squares come out

One grid on A4, after a twelve-millimetre margin, lands around twenty-five millimetres a square. That is larger than the four-up sheet and much larger than six-up. There is leftover margin for a note about which puzzle this is, or for a short chain of reasoning you do not want to hold in your head.

The print stylesheet keeps a single column and hides the rest of the site, so the browser cannot scale the grid down to make room for a header it was told to hide. What you see in the print preview is the sheet. If the preview shows a second blank page, something else on the machine is adding a margin; the CSS here does not.

Box borders print as real black, not a light grey economy mode can drop. On a large grid that is the only thing keeping the nine boxes visible as boxes. Lose it and you are solving eighty-one loose squares.

When one grid is the right number

When the puzzle will take more than one sitting. A hard grid left on a kitchen table overnight is still there in the morning, with the candidates still legible, which is not true of a six-up sheet that has been folded around a mug.

When you are copying from a book or a screen for someone else. The clues transfer once, at a size they can mark, and you are not asking them to work at newspaper scale because that was the only printout in the house.

When you want two attempts, print this page twice rather than asking one large grid to share the paper. Two-up is the layout for a pair of working copies; this URL is the layout for a single readable board. The six-up blank page remains the paper-saver for copying several puzzles in one go.

Common questions

Is this a large-print Sudoku puzzle or just a bigger empty grid?

An empty grid. You copy the clues on. The squares are about 25 mm so the marks stay readable; it is not a daily puzzle booklet.

How large are the squares on the large-print sheet?

About twenty-five millimetres on A4, one grid to the page. That is the size that keeps a digit and its candidates from colliding.

Can I print more than one large grid at a time?

Raise the count in the box if you want extra sheets. Each grid still prints at large-print size; they will not shrink back to six-up unless you switch pages.
