How to make a printable crossword puzzle

1. Enter one word per line followed by its clue, separated by a colon — for example rain : Water that falls from clouds. Lines without a clue simply use the word itself as a fill-in item.
2. Click Generate crossword. The words are automatically interlocked into a compact grid with numbered Across and Down clues.
3. Click Print / Save PDF. The puzzle prints with a name and date line; if the answer key is ticked, a filled-in grid prints as a second page.

Crosswords with an answer key

Tick Answer key and the printout adds a second page with every letter filled in. On screen, the same toggle reveals the letters so you can check the layout before printing. This is the fastest way for teachers to grade a vocabulary crossword — print once for the class, keep the key page for yourself.

Crosswords with a word bank

The word bank option prints all the answers in a dashed box between the grid and the clues. Students still have to match each word to the right clue and fit it in the grid, but they aren't stuck guessing spelling — ideal for younger students, spelling practice and foreign-language vocabulary.

Choosing words that interlock well

A crossword is built from shared letters, so the composition of your word list decides how good the grid looks. Words rich in common letters — A, E, I, O, R, S, T, N — connect easily. Words built from J, Q, X and Z tend to dangle off the edge or fail to place at all. If a grid comes out sparse and stringy, the usual cause is a list of words that have little in common rather than anything to do with the settings.

Length matters too. A list of uniformly short words produces a cramped grid with few crossings; a mix of 4–10 letter words gives the generator long spines to hang shorter words from. Twelve to twenty words is a good target for a single page — beyond that the grid grows faster than the page does, and the printed squares get small enough to be awkward to write in.

Writing clues that work

The clue does more work than the word. For classroom use, definition clues ("Water that falls from clouds") test whether a learner knows the term, while fill-in-the-blank clues ("It began to ___ heavily") test usage in context — the second kind is much better for language learners, because it puts the word in a sentence. Mixing both keeps a puzzle from feeling mechanical.

Keep clues shorter than about eight words so the clue list stays on one page, and avoid giving away the letter count in the clue itself — the grid already does that. One thing worth checking before you print: make sure no clue accidentally contains its own answer, which is easy to do with compound words and instantly deflates the puzzle.

Using crosswords for vocabulary and revision

Crosswords suit recall practice better than word searches do, because the solver has to produce the word from its meaning rather than merely spot it. That makes them a good fit for end-of-unit revision, foreign-language vocabulary, and technical terminology in subjects like biology or history.

Two settings make the same puzzle work for a mixed-ability class. Tick the word bank for learners who need support — they still have to match each answer to the right clue and fit it into the grid, but they are not staring at a blank page. Leave it off for everyone else, and print one answer-key copy for yourself so marking takes seconds rather than minutes.

Why won't all my words fit?

Words can only join the puzzle where they share a letter with a word already placed. If a word has no letters in common with the rest of your list, the generator tells you which ones it couldn't connect — swap them for related words with common letters, or simply generate again for a different arrangement.

Is my word list uploaded anywhere?

No. The puzzle is built locally in your browser with JavaScript — your words, your clues, the grid and the printed page never leave your device, and the tool works offline once loaded.

There is exactly one exception, and only if you choose to use it. The Write the list for me box sends the topic you type to our server, which passes it to an AI provider to write the words and clues. That topic is the only thing transmitted: not your edited word list, not the finished puzzle. We do not store it. If you never use that box, nothing at all leaves your browser.
