How to print a tangram set that actually fits together

  1. Print at 100% scale. In the print dialog, set scaling to 100% (or "Actual size") rather than "Fit to page". Shrinking the page shrinks the pieces, and a set printed at two different scales will never assemble.
  2. Use the heaviest paper your printer takes. 160–250 gsm card keeps the tans flat and stops thin points from curling. Ordinary paper glued to cereal-box card works just as well.
  3. Cut along every line. The pieces tile their square exactly, so each line is shared by two pieces, and cutting once separates both.
  4. Keep the square as a check. If the pieces go back into the shape they came from, the set was cut accurately enough for every other puzzle.

What's in each sheet

Cut-out piece set
A set's pieces, laid out as the square they are cut from.
Puzzle silhouettes
One to four shapes per page, solid or outlined, with no inside lines. Every one is solvable.
One scale for the set
The pieces and the shapes print at the same size, so the pieces you cut out fit straight onto the shapes. Fewer shapes per page means bigger pieces.
Solutions
The same shapes with the pieces drawn in, six to a page.

Prefer to solve on screen? The same shapes are playable in the online tangram game, and the background page covers the history of the puzzle.
