Printable tetrominoes
Free printable tetrominoes you can download as PDF right away: five 4-square pieces to cut out, blank boards to fill, and worksheets with an answer key. Choose A4 or Letter, then print or Save as PDF—no account needed.
The five free tetrominoes (I, O, T, L, S), spaced so you can cut along the thick lines. Glue onto thin card first if you like. Each square is ¾ inch (19 mm), the same size as the blank boards. L includes its mirror; S includes its mirror when you flip the piece.
Fill every square with two copies of I, O, L and S (no T). The T piece covers three squares of one chessboard colour, so a plain rectangle needs an even number of T pieces.
Use two of each free tetromino (I, O, T, L, S). Forty squares, many solutions — a good classroom race board.

A tetromino is a polyomino of order 4: four equal squares joined edge to edge. Teachers and puzzle fans look for printable tetrominoes when they want cut-outs for a lesson, a quiet table activity or a take-home worksheet. This page is built for that intent — Print / Save as PDF, A4 or Letter, no account — rather than an on-screen falling-block race.
The five free shapes are enough for rich packing questions. One of each covers twenty squares, yet a plain 4 × 5 rectangle is impossible because of the T colouring argument above. Give pupils two of each piece and a 5 × 8 board (forty squares) and the problem opens up. Skip the T and use two each of I, O, L and S on a 4 × 8 board for a slightly easier set. Our worksheets go further: every little box and every finish-the-rectangle puzzle was filtered so the solver finds exactly one answer.
If you need five-square pieces instead, use the matching printable pentominoes page. For screen practice with drag, turn and flip, open the free tetromino puzzle. To see how tetrominoes sit among trominoes, pentominoes and hexominoes, read what polyominoes are or play the polyomino packing game.

Each square is ¾ inch (19 mm) when printed at 100% scale. Blank boards use the same square size so cut-outs fit the grids.
Shapes of four equal squares joined edge to edge. Allowing turns and flips there are five: the straight (I), square (O), T, skew (S) and L. The L piece covers its mirror image when flipped; the same for S.
No. These are calm packing shapes for cutting, boards and worksheets. Nothing falls and there is no timer. For an on-screen packing game, play our free tetromino puzzle.
The five pieces cover 20 squares, but the T covers three squares of one chessboard colour and one of the other. A rectangle has equal dark and light squares, so a single T never fits. That is why the blank boards use two of each piece (or skip T on the 4×8).
Worksheet 1 starts with a 4×2 box of two pieces (about age 6+) and builds up to a 5×4 box. Worksheet 2 suits older children and adults. Every puzzle has a single solution.
