Choosing Readable Grid and Font Sizes

A readable printed word search needs grid letters of roughly 12 points or more for most adults and 18 points or more for large print, a word list that’s easy to scan, and a grid small enough to fit those letters on one page. On a standard US Letter page, an 18-point grid can be at most 18×18; on A4, 17×17. This guide explains where those numbers come from and how to choose sizes on purpose.

Points, pixels and why “big on screen” isn’t enough

Printed text is measured in points: 72 points make one inch (about 2.54 cm). A typical paperback uses body text around 10–11 points. Large print books commonly use 16 points or more, and many large print guidelines recommend at least 16–18 points.

Screens are different. A grid that looks huge on a laptop can print surprisingly small, because the printer fits the whole page onto paper. That’s why this site lays out PDFs in points and states the actual sizes — “large print” here is a measured promise, not a look.

The three sizes that matter

1. Grid letter size

This is the size of each letter in the puzzle. On this site:

• Standard letters are sized to fill the page, between 9.5 and 20 points depending on grid size.
• Large print letters are at least 18 points, up to 26 points for small grids.

2. Cell size (the spacing)

Each letter sits in an invisible square cell. Letters take up about 60% of the cell, leaving space between neighbors so the eye can follow a line. For 18-point letters, each cell is 30 points — just over 4 mm.

3. Word list size

The checklist of words: 11.5 points standard and 16 points in large print. Each word has a small checkbox for crossing it off.

How big can the grid be?

The printable width of a page sets a hard limit. With half-inch margins:

Paper	Printable width	Largest standard grid	Largest large print grid (18 pt)
US Letter (8.5 × 11 in)	540 pt	33×33*	18×18
A4 (210 × 297 mm)	about 523 pt	32×32*	17×17

*The maker’s grids top out at 25×25, so every grid fits on one page at standard size.

The arithmetic for large print on Letter: 540 points ÷ 30-point cells = 18 cells. A 20×20 grid would need cells of 27 points and letters of about 16 points — no longer large print. Instead of quietly shrinking it, the site tells you and suggests a smaller grid or standard size.

Choosing a grid size for the reader

Reader	Suggested grid	Print size	Difficulty
Young children (5–7)	8×8 to 10×10	Large print	Easy
Older children	10×10 to 15×15	Standard	Easy or Medium
Most adults	13×13 to 20×20	Standard	Medium or Hard
Readers who prefer bigger text	10×10 to 17×17	Large print	Any
Puzzle enthusiasts	18×18 to 25×25	Standard	Hard

Notice that difficulty and size are separate decisions. A Hard puzzle, with words running backward and diagonally, can absolutely be printed in large print — just keep the grid at 17×17 or smaller.

On screen: zoom without squinting

When playing online, the board picks a comfortable square size for your screen. Below the board:

• Zoom in / out buttons change the square size from 60% to 200%, and your choice is remembered.
• When a board is wider than the screen, it scrolls inside its own frame rather than shrinking letters below a readable size. Squares never get smaller than 24 CSS pixels in play.
• On touch screens, a Selecting words / Moving board button switches between selecting and scrolling the board.

Your browser’s own zoom and text-size settings work as well. More detail in playing with a keyboard, touch, or larger text.

Printing so the sizes stay true

Sizes are only accurate if the printer doesn’t rescale the page:

1. Download the PDF rather than using quick print.
2. In the print dialog, choose Actual size or 100% — not “Fit.”
3. Match the paper size to what’s in the printer.

Each page footer repeats “Print at actual size (100%)” as a reminder. Read printing on US Letter and A4 for more.

What size will my letters be?

Because letters are sized to fill the page width, the grid size decides the letter size. These are approximate grid letter sizes at 100% scale:

Grid	Standard, Letter	Standard, A4	Large print, Letter	Large print, A4
10×10	20 pt	20 pt	26 pt	26 pt
15×15	20 pt	20 pt	about 22 pt	about 21 pt
17×17	about 19 pt	about 18.5 pt	about 19 pt	about 18.5 pt
18×18	18 pt	about 17.5 pt	18 pt	not available
20×20	about 16 pt	about 15.5 pt	not available	not available
25×25	about 13 pt	about 12.5 pt	not available	not available

Two details explain the table. Standard print is capped at 20 points, because bigger letters in small grids look childish and waste paper. And when a long word list would otherwise spill onto a second page, the layout may shrink the grid slightly — but never below the minimum for that print size. Large print letters never drop below 18 points.

The practical rule: if a reader needs letters of a certain size, choose the grid size first. For 16-point letters on standard print, stay at 20×20 or smaller; for 18-point large print, 18×18 on Letter or 17×17 on A4.

Viewing distance

Letter size and distance work together. A puzzle held in the hands at reading distance is comfortable at 12–14 points for most adults. A puzzle lying flat on a table is further away and seen at an angle, so a bigger size helps. A puzzle pinned to a wall or shown to a group needs much larger letters still — for a group, it’s better to give everyone their own copy than to enlarge one.

Readability for children

Children reading early benefit from larger letters and fewer of them. For ages about 5 to 7, use an 8×8 to 10×10 grid in large print: letters are around 26 points and each cell is wide enough for small fingers and crayons. Keep the word list short, so it fits under the grid in one or two columns. As reading improves, move to standard print and bigger grids before moving up in difficulty.

Frequently asked

Why don’t you offer a 30×30 grid? At 25×25, standard letters are already around 13 points on paper. Larger grids would push letters toward 10 points, which tires most solvers. The maker stops at 25×25 for that reason.

Is bold text easier to read? The grid letters use a bold weight of a typeface designed for legibility. Heavier still would make letters run together at small sizes.

Why is my on-screen board smaller than the printed one? Screen and paper are sized separately. On screen, the board fits your window, and you can zoom it; the PDF uses the fixed sizes above.

Typeface matters too

Size isn’t everything. The letters on this site use Atkinson Hyperlegible Next, a typeface created for the Braille Institute of America to keep similar characters distinct for readers with low vision — for example, a capital I and a lowercase l, or O and 0. You can read about its design on the Braille Institute’s website. The PDF embeds the same font, so printed letters match the screen.

In a word search, every letter is uppercase, which helps further: uppercase letters are all the same height and easy to compare.

Common mistakes

• Choosing a big grid “to make it harder” and then printing large. The two goals conflict on paper. Make it harder with Hard difficulty instead.
• Photocopying at reduced size to fit two puzzles per page. That halves the letter size; use smaller grids instead.
• Printing on A4 from a Letter PDF. The printer scales to fit, slightly shrinking everything.

When in doubt, print one copy and hand it to the person who’ll solve it. Their reaction tells you more than any table: if they lean in or reach for glasses, go a grid size smaller or switch to large print.

Readable puzzles are kinder puzzles: when people can see the letters easily, they spend their effort on the search itself, which is where the fun is.

Size, spacing, typeface and contrast work together; get all four right and almost anyone can enjoy the puzzle.

Summary

• Large print here means 18-point letters minimum and a 16-point word list.
• Large print grids top out at 18×18 on Letter and 17×17 on A4.
• Make puzzles harder with directions, not tiny letters.
• Print the PDF at 100% for true sizes.
