Crocheted cubes and cuboids can be used especially well for amigurumi as heads and body parts of robots and machines or angular animals, or as dice with embroidered numbers or if crocheted larger with an open or hinged side, as a storage box.
A crochet cube in spiral rounds is similarly crocheted as a ball. First you start with the bottom of the cube, a square, then you crochet the sides of the cube till you reach your desired height and then close the cube with another square.
Since the height can be crocheted as high as you like, you can also crochet a cuboid (a three-dimensional rectangle) from the cube by simply crocheting higher than the initial square is wide.
The here depicted cube has been crocheted with the “Schachenmayr Catania” yarn with a 2.5 mm crochet hook.

- Stone (Stein (242)), Blue (Kachelblau (380))
- 2.5 mm Crochet Hook

Crochet Cube Pattern
Crochet the cube with single crochet stitches in spiral rounds. The cube in Stone is almost completely crocheted into the front loop, while the cube in Blue is crocheted into both loops, except for the edges.
The difference, apart from a slightly different stitch pattern, is that crochet pieces which are crocheted in spiral rounds in both loops shift slightly from round to round, while the piece crocheted only in the front loop always remains in the same starting position from round to round.
Therefore you have to adjust the last round when crocheting into both loops with a few extra stitches before you start crocheting the final top square that closes the cube. Otherwise the whole cube would be twisted and the upper and lower square would not lie correctly on top of each other.
Use the check boxes to mark your finished rounds, rows and steps.
- Crochet the cube in spiral rounds in Blue or Stone. The cube in Stone is only crocheted into the front loop, the cube in Blue is crocheted into both loops, except if the instructions say otherwise.
- Round 1: 4 sc into the Magic Ring (4 stitches).
- Round 2: [3 sc into the next stitch] repeat till end of the round (12 stitches).
- Round 3: 1 sc, [3 sc into the next stitch, 2 sc] repeat 3 times, 3 sc into the next stitch, 1 sc (20 stitches).
- Round 4: 2 sc, [3 sc into the next stitch, 4 sc] repeat 3 times, 3 sc into the next stitch, 2 sc (24 stitches).
- Round 5: 3 sc, [3 sc into the next stitch, 6 sc] repeat 3 times, 3 sc into the next stitch, 3 sc (36 stitches).
- Round 6: Crochet the complete round into the back loop only. Crochet 36 sc (36 stitches).
- Round 7-14: 8 rounds (or 7 rounds for the cube in Stone, because the rounds are higher when crocheted only into the front loop), each round 36 sc (36 stitches).
You can adjust the size or height of the final cube yourself by crocheting more or less than 8 rounds in height. As long as the height is the same or about the same as the bottom is wide, you get a cube, if you crochet higher than the width, you get a cuboid.
As you can see, the last stitch of the cube in Blue is not centered as it is the case with the cube in Stone. Therefore you have to adjust this with some stitches before you start crocheting the final square.
This always has to be adjusted individually. The higher the cube/cuboid, the more the last round is shifted. Always make sure that the corners of the upper square are approximately at the same position as the corners of the lower square, otherwise the cube/cuboid will end up twisted.
- Round 15: Crochet only 2 sc for the cube in Blue.
- Round 16: Crochet the complete round into the back loop only. 3 sc, [sc 3 together, 6 sc] repeat 3 times, sc 3 together, 3 sc (28 stitches).
- Round 17: 2 sc, [sc 3 together, 4 sc] repeat 3 times, sc 3 together, 2 sc (20 stitches).
- Round 18: 1 sc, [sc 3 together, 2 sc] repeat 3 times, sc 3 together, 1 sc (12 stitches).
- Round 19: [sc 3 together] repeat 4 times (4 stitches).
- Finish: Cut the yarn, close the opening, weave in and hide the leftover yarn.
Crochet Your Own Cubes and Cuboids
Always remember that you have to adjust the upper, final square of a cube if you crochet into both loops, since the starting position shifts slightly from round to round.
Crochet as many extra stitches until the first corner of the upper, final square is at the same postion as one corner of the lower square on the underside.
If you want to crochet a cube with round edges, instead of crocheting into the back loop to create the edge, crochet through both loops.
Likewise, instead of closing the cube with a square you also can close it with a circle, by spreading the increases over more stitches, thus obtaining completely new shapes.
