Learn how to crochet triangles and find the perfect triangle for your next project in this collection of free patterns and tutorials.
When you want to crochet a triangle, there are many ways you can go about it. Ideally, you can crochet a triangle from the bottom up, top down, side to side, etc.
The possibilities and the stitch patterns are endless. That’s why in this post, I’m not claiming to give you an exhausting list of crochet triangle patterns.
Instead, I tried to cover the basic shapes and techniques that you can use to crochet a simple triangle using the basic stitches, mostly single crochet and double crochet.
For clarity, I grouped the 11 crochet triangles that we’ll see here into 3 categories:
- Triangles worked in rows from the bottom up, so, starting from the tip (one vertex) and moving to one side;
- Equilateral triangles crocheted in the round;
- Triangles crocheted from the center out – these are the classic half granny triangles and triangle shawl patterns, just to be clear.
For the first category (triangles worked in rows), you’ll find the patterns directly on this page, while for the other triangles, you’ll find links to the appropriate tutorial.

Crochet Triangles in Rows Bottom-Up
The easiest way to crochet a triangle is to crochet in rows, turning your piece at the end of each row. You can crochet this kind of triangle using any stitch combination.
Here, however, I’ll give you three examples, the first two using single crochet and the third using double crochet stitches.
- 1 – Single crochet triangle with increases at both ends of each row
- 2 – Single crochet triangle with increases only at the beginning of each row
- 3 – Double crochet triangle with increases at both ends of each row
I chose these examples because I thought they were the most helpful in understanding how the shape of your triangle can change based on the number of increases you make at each row, and the height of the stitch you use!
It’s also worth mentioning that you can crochet a triangle from the tip to the side using the granny stitch using the C2C granny stitch. Of course, you’ll increase until you’re happy with the size of your triangle, and you’ll never get to the decrease part of the C2C granny stitch.

But let’s go back to the examples of triangles using single and double crochet stitches…
1 – Single Crochet Triangle
Ch 2.
Row 1. Sc 1 in the second ch from hook. (1 sts)
Row 2. Ch 1 (does not count as a st here and throughout), and turn. Sc inc 1. (2 sts)
Row 3. Ch 1, turn. Sc inc 2. (4 sts)
Row 4. Ch 1, turn. Sc inc 1, sc 2, sc inc 1. (6 sts)

To grow your triangle, increase by two stitches per row: one increase at the beginning and one increase at the end.
2 – Single Crochet Triangle

To grow your triangle, increase by one stitch at the beginning of each row.
3 – Double Crochet Triangle
Ch 4.
Row 1. Dc 2 in the first-made ch (turning ch-3 counts as a dc). (3 sts)
Row 2. Ch 3 (counts as dc here and throughout), or ch-less dc 1. Dc 1 in the first st, dc 1, dc inc 1. (5 sts)
Row 3. Ch 3 or ch-less dc 1. Dc 1 in the first st, dc 3, dc inc 1. (7 sts)
Row 4. Ch 3 or ch-less dc 1. Dc 1 in the first st, dc 5, dc inc 1. (9 sts)
Row 5. Ch 3 or ch-less dc 1. Dc 1 in the first st, dc 7, dc inc 1. (11 sts)
Row 6. Ch 3 or ch-less dc 1. Dc 1 in the first st, dc 9, dc inc 1. (13 sts)
Row 7. Ch 3 or ch-less dc 1. Dc 1 in the first st, dc 11, dc inc 1. (15 sts)
Row 8. Ch 3 or ch-less dc 1. Dc 1 in the first st, dc 13, dc inc 1. (17 sts)
Row 9. Ch 3 or ch-less dc 1. Dc 1 in the first st, dc 15, dc inc 1. (19 sts)
To grow your triangle, increase by two stitches per row: one increase at the beginning and one increase at the end.
Crochet Triangles in the Round
The second category that we’ll see is the one of triangles crocheted in the round.
When you crochet a triangle in the round, you get a nice edge all around, which is very convenient if you want to join your triangles to other elements (squares, rectangles, etc).
These triangles are equilateral triangles, meaning that all the sides are the same length.
You can crochet triangles in the round using ideally any stitch. Here, we’ll see the following patterns:
- 5 – Single crochet triangle in the round;
- 6 – Granny stitch triangle in the round;
- 7 – Classic, solid double crochet triangle in the round;
- 8 – Solid triangle in the round without any gaps.
5. Single Crochet Triangle in the Round
The single crochet triangle in the round is very useful for making Amigurumi, toys, sturdy home decor items, etc.
- Get the free pattern of the single crochet triangle in the round HERE.
Then, we have three types of crochet triangles in the round that use the double crochet stitch (see the picture below).
6. Granny Square Triangle
- Find the free pattern of the granny stitch triangle in the round HERE.
7. Solid Triangle
If you want a double crochet triangle in the round with a more solid fabric, this might be the right pattern for you.
- Find the free pattern HERE.
8. Solid Triangle without Gaps
If you want your triangle without any gaps at all, then, you might want to check the pattern of the (mostly) double crochet solid triangle in the round without gaps HERE.
Crochet Triangles from the Center-out
Last but not least, we have the category of triangles crocheted from the center out.
The first three of these triangles (triangles 1 to 3 in the picture below) are right angles since they are exactly half a square along the diagonal.
The last square (number 4 in the picture below) is an isosceles, obtuse triangle that is perfect for making shawls and scarves.
- 9 – Half granny square triangle (number 1 in the picture above)
- 10 – Half solid square triangle (number 2 in the picture above)
- 11 – Half solid square triangle without any gaps (number 3 in the picture above)
- 12 – Double crochet triangle for scarves and shawls (number 4 in the picture above)
9. Half Granny Square Triangle
The half granny square triangle is a classic shape and corresponds to half a classic granny square when you fold it along one of its diagonals.
This triangle works great for filling gaps at the edges of blankets, shaping granny square cardigans and garments, making granny shawls, and so much more.

10. Half Solid Square Triangle
In a similar way to crocheting half a granny square, you can crochet a half solid square triangle. This triangle is half a solid granny square when you fold the square along its diagonal.
This triangle has the advantage of having fewer holes than a classic granny stitch triangle and it’s great for making a warm and cozy fabric.
- Find the free pattern of the half solid square triangle HERE.
11. Half Completely Solid Square Triangle
If you’re aiming for a completely solid fabric that is warm and perfect for the colder months, you might want to check this half solid square without any gaps at all.
This triangle is the half of the completely solid square without any gaps (not even at the vertices!).
- Get the free pattern of the half solid square triangle without gaps HERE.
12. Double Crochet Triangle (Useful for Shalws!)
The last triangle of the collection is this less-deep triangle that is perfect for making shawls and scarves. If you join two of these triangles, you won’t get a square but something more similar to a diamond!
