How to Make a Word Search Puzzle (Grid Sizes and Tips)

⏱️ 6 min readUpdated September 26, 2026

To make a word search, choose a theme, write a list of 8 to 12 words, and draw a square grid (10x10 is a good start). Place the longest words first, mix the directions, copy the finished layout as your answer key, then fill every empty square with random letters. The rest comes down to grid size, word count, directions and filler letters.

How do you make a word search by hand?

You need graph paper, a pencil and about 20 minutes for a 10x10 puzzle.

  1. Pick a theme and a word list. Ocean animals, this week's spelling words, guests at a baby shower. Write them in capitals.
  2. Draw the grid. Outline a square on graph paper, one letter per box.
  3. Place the longest words first. A 10-letter word in a 10x10 grid has few spots left once others are down.
  4. Mix the directions. Put some words across, some down and a few on the diagonal.
  5. Cross words where letters match. If DOLPHIN runs across and SHARK runs down, they can share the H.
  6. Make the answer key before you fill. Trace the grid while only your words are on it and highlight each one.
  7. Fill the blanks. Put a letter in every empty square.

After filling, read along the rows. Random letters can spell an accidental rude word, and kids will find it before anything on your list.

What grid size should you use?

Grid size sets two hard limits. The longest word can't be longer than the grid is wide, whether it runs across, down or diagonally. And the number of squares caps how many words fit. The ranges below match our word search maker

Our maker offers 10x10, 12x12, 15x15 and 20x20, with a switch to turn diagonal words on or off. For an 8x8 or 18x18, graph paper is the way to go.

How many words fit in a word search?

The comfortable range is roughly one word for every 8 to 12 squares, which is where the table's "squares per word" column lands for most sizes.

Direction choice changes the math more than people expect. Take a single 5-letter word in a 10x10 grid. If you only allow across and down, it has 120 possible positions. Add the two downward diagonals and that rises to 192. Allow all eight directions, backwards included, and it's 384. More positions means more places to check, which is why eight-direction puzzles feel harder.

If you're turning a paragraph of notes into a word list, paste it into the word counter first to see how many words you're working with.

How do you make a word search harder or easier?

A handful of settings do most of the work. Change one or two at a time.

SettingEasierHarder
Directions2 (left to right, top to bottom)All 8, including backwards and upward diagonals
Filler lettersRandom A–Z, with rare letters like Q, X and Z standing outDrawn only from letters in your word list, so fake near-misses appear
Word lengthLong words (7+ letters)Short words (3–4 letters)
Grid sizeSmall grid, fewer rows to scanLarge grid, 15x15 or bigger
Word listPrinted beside the gridHidden, or given only as clues
ThemeMixed words with distinct lettersOne tight theme with similar spellings (TROUT, TROUGH)
OverlapsFew, words sit apartMany, words cross and share letters

The filler trick is the sneakiest: a solver hunting for PENGUIN keeps hitting dead-end fragments like PEN and GUI.

How do you make one for kids vs adults?

For kids aged 5 to 7, keep it to an 8x8 or 10x10 grid, 6 to 10 words, across and down only. Use large capitals, and add a small picture beside each listed word for early readers.

For older kids, add diagonals and bump up to a 12x12. Build the list from spelling words and it doubles as a vocabulary drill. If you add an anagram round, the word unscrambler can check your answer key if you mix in an anagram round.

Adults usually want a 15x15 or 20x20 with all eight directions and 20 or more words. For a birthday or retirement party, fill the list with inside jokes, places and people from the guest's life.

How do you print it and make an answer key?

If you drew it by hand, photograph the grid before filling; that becomes the answer key. Print class keys on colored paper so they don't end up in the stack.

Using a generator, print the puzzle straight from the browser. Set margins to minimum, scale to fit one page, and use at least 14-point letters for young eyes. If your tool doesn't print a key, solve it once yourself and circle the words on a copy. It catches any word that quietly didn't make it into the grid.

Word search vs crossword: what's the difference?

A word search gives you the answers and asks you to find them. A crossword gives you clues and asks you to work out the answers.

Word searches are also far easier to build, since there are no clues to write and the filler covers any gap.

The format is fairly young. Norman E. Gibat published one in the Selenby Digest, a free want-ad paper in Norman, Oklahoma, on March 1, 1968. It hid 34 Oklahoma town names in a 20x20 grid. Spain's Pedro Ocón de Oro is also credited with an early version, so the "first" title is disputed.

The bottom line

Choose a grid that fits your longest word and your word count, place the long words first, and make the answer key before a single random letter goes in. For a classroom sheet, 10x10 with 10 words and no backwards words is hard to beat.

Frequently Asked Questions

How do you make a word search by hand?

Pick a theme and list your words, then draw a square grid on graph paper. Write the longest words in first, mix across, down and diagonal placements, and copy the grid as an answer key. Only then fill every empty square with random letters.

What size grid do I need for a word search?

Match the grid to the word count. An 8x8 grid holds about 6 to 8 words for young kids, a 10x10 holds 8 to 12, a 15x15 holds 15 to 25 and a 20x20 holds 25 to 35. Your longest word also can't be longer than the grid is wide.

How many words should a word search have?

Plan on about one word for every 8 to 12 squares. A 10x10 grid has 100 squares, so 8 to 12 words is the comfortable range. Fewer words leaves the puzzle mostly filler, and more forces heavy overlaps.

How do you make a word search harder?

Allow all eight directions, including backwards and diagonal words, use a bigger grid, pick shorter words and draw your filler letters from the letters in your word list. Words that share the same theme also make it harder, because the solver can't guess by category.

Can you make a word search with overlapping words?

Yes. Two words can cross wherever they share a letter in the same square, like CAT and TOP sharing the T. Overlaps save space and make the grid denser, but check the answer key carefully so no shared letter is wrong for either word.
