Word Search Maker
Type your own words and print a custom word search, with an answer key one tick-box away. Free, instant, and it runs entirely in your browser — nothing is uploaded.
How to use it
- Give the puzzle a title — a spelling list, a topic, a birthday child’s name.
- Type your words, one per line. Up to 20; keep each shorter than the grid.
- Pick a grid size. 8–10 suits young children; 14–18 makes a harder puzzle.
- Turn off diagonal and backwards words for early readers. Hit Shuffle for a different arrangement of the same words.
- Tick the answer key and print that copy for yourself, then untick it and print the class set.
Grid size and word count by age
The commonest mistake is a grid that is too big. A 15×15 puzzle with eight short words is mostly filler, and a six-year-old will give up on it long before they find anything.
| Age | Grid | Words | Directions | Word length |
|---|---|---|---|---|
| Pre-K and reception (4–5) | 8×8 | 6–8 | Across and down only | 3–5 letters |
| Years 1–2 (6–8) | 8×8 to 10×10 | 8–10 | Across and down only | 3–6 letters |
| Years 3–5 (8–11) | 12×12 to 14×14 | 12–15 | Add diagonals | up to 8 |
| Secondary and adult | 16×16 to 18×18 | 15–20 | Add backwards | up to the grid width |
Why diagonals and backwards are separate switches here
Most makers bundle them into one “hard mode” checkbox. They are not the same difficulty. Diagonals add axes to scan, which is a matter of patience. Backwards words fight the reading direction a child has spent years automating, which is a matter of ability — and it is why a puzzle can feel unfair rather than hard.
A useful order: across and down until reading is fluent, then diagonals from about year 3, then backwards for older children and adults.
The number that actually sets the difficulty
Grid size on its own is misleading. What matters is how much of the grid the answers occupy: letters used, divided by cells available. Ten six-letter words in a 15×15 grid fill 60 of 225 cells, about 27%, which is comfortably easy. Below roughly 20% the words are lost in filler. Above roughly 45% they start crossing each other so often that the shared letters give the positions away — so past a point, adding more words makes a puzzle easier. The sweet spot for most classroom puzzles is 25–40%.
Words that break word searches
- One word inside another. CAT hidden inside CATTLE gives two correct-looking answers and one argument. Keep the list free of substrings.
- Two-letter words. They appear by accident everywhere in the filler and are effectively unfindable.
- Spaces and hyphens. ICE CREAM and T-SHIRT are stripped to ICECREAM and TSHIRT, so print the word bank with the punctuation the children expect.
- Plurals of words already on the list. DOG and DOGS overlap almost entirely and read as the same find.
- Words longer than the grid. The tool tells you rather than dropping them quietly — widen the grid or shorten the word.
Classroom workflow
Paste this week’s spelling list straight into the box — one word per line, or comma-separated, either works. The same route covers sight words, unit vocabulary, a Friday review, or a topic list for a supply teacher.
Turn on the name-and-date line before printing a class set. Print one copy with the answer key showing for yourself, then untick it for the rest. Letters are always capitals: for a child still learning letter shapes, matching mixed case is two jobs rather than one, and capitals remove the ascender and descender cues that let a skimmer cheat.
For a set you will use again and again, laminate one and hand it over with a dry-erase marker — the same trick that works for laminated colouring pages.
Beyond the classroom
- Large print for older solvers. An 8×8 or 10×10 grid on Letter gives the biggest letters this tool can produce, which suits low vision and memory-care activity sessions.
- Party puzzles. Guest names for a wedding table, baby-name lists for a shower, or the birthday child’s favourite things.
- Language learning. A vocabulary set as a word search forces letter-by-letter attention in a way a list never does.
- Waiting rooms and long journeys. One puzzle, one pencil, no battery.
Frequently asked questions
How many words can I add?
Up to 20. If a word will not fit, the tool tells you rather than silently dropping it — increase the grid size or shorten the word.
Is there an answer key?
Yes. Tick “Show the answer key” and every word is highlighted in the grid. Print or download that copy for yourself, then untick it and print the puzzle for everyone else.
Can I make it easier for young children?
Yes. Use an 8×8 or 10×10 grid, six to eight short words, and turn off both diagonal and backwards so every word reads left to right or top to bottom.
What size grid should I use?
For ages 4–5, 8×8 with six to eight three-to-five-letter words. For 6–8, up to 10×10. For 8–11, 12×12 to 14×14 with diagonals. For teenagers and adults, 16×18 with backwards words on.
Why are the letters always capitals?
Because matching mixed-case letters is two tasks for a child who is still learning letter shapes, and lowercase ascenders and descenders make it easier to spot words without really reading them.
Can I save it as a PDF?
Print the page and choose "Save as PDF" as your printer. That gives a clean single-page PDF with no browser headers.
Do you store my words?
No. Everything is generated in your browser; nothing is sent to a server, which is also why there is no limit on how many you make.
Can I use these in class or sell them?
Print freely for your classroom or family. Selling the generated sheets, or publishing them in a book for sale, is not permitted.
