How to Crochet a Rectangle (Straight, Even Sides)
The rectangle is the most common shape in crochet, and the one you will make more than any other. Blankets, scarves, dishcloths, bags, and garment panels are all rectangles at heart, so learning to crochet a neat rectangle with straight, even sides is a core skill. It sounds simple, and it is, but keeping the sides truly straight takes a couple of good habits. This guide shows you how to crochet a rectangle and keep it even. It is part of the crochet shapes guide.
What Is a Crochet Rectangle?
A crochet rectangle is a flat, four sided shape worked back and forth in rows, with the width set by your foundation chain and the length built up row by row. Unlike shapes worked in the round, a rectangle is made in straight rows, turning at the end of each one. Because it is so fundamental, the rectangle is really just plain rows of crochet, which means the whole challenge is keeping those rows even so the sides stay straight and the corners stay square.
Set the Width With Your Chain
The width of your rectangle is decided by your foundation chain, so you start by chaining the number of stitches you want across, plus the turning chain your stitch needs. A longer chain makes a wider rectangle. If you want a rectangle a certain size, you can make a small gauge swatch to see how many stitches fit in an inch, then chain accordingly. Getting the foundation chain right, and not too tight, sets you up well, and there is more on chains in how to crochet a chain stitch.
Step by Step: How to Crochet a Rectangle
Step one: make a foundation chain the width you want, plus your turning chain. Step two: work your chosen stitch, such as single or double crochet, into the chain across the first row. Step three: at the end of the row, make your turning chain and turn the work. Step four: work the next row into the stitches across, keeping the same number of stitches. Step five: repeat, row after row, until the rectangle reaches the length you want. Fasten off and weave in the ends. The key throughout is keeping the stitch count the same in every row.
Keeping the Sides Straight
The one thing that makes or breaks a rectangle is a steady stitch count, because if the count drifts, the sides slant or wave instead of running straight. Count your stitches at the end of every row and compare to your starting number, and place a stitch marker in the first and last stitch of each row so you never add or miss one at the edges. Handling your turning chain the same way every row matters too. These habits, covered in why are my crochet edges not straight, keep the rectangle even.
Choosing Your Stitch
Any stitch makes a rectangle, so choose based on the fabric you want. Single crochet makes a dense, firm, sturdy rectangle, good for dishcloths, bags, and anything that needs structure. Double crochet is taller and quicker, ideal for blankets and scarves where you want speed and drape. Textured and patterned stitches work too, as long as you keep the stitch count even. The rectangle is a great canvas for trying out different stitches from the crochet stitch library.
Common Rectangle Mistakes
The most common mistakes are a stitch count that drifts, making the rectangle get wider or narrower, and a foundation chain that is too tight, which pulls the bottom edge in. Count each row and keep your chain relaxed to avoid both. Uneven tension can make the fabric look wavy even when the count is right, which blocking helps settle. If your rectangle is changing width, the guide to why is my crochet getting wider or narrower will help you fix it.
What You Can Make
Rectangles are the foundation of blankets, scarves, dishcloths, table runners, cushion covers, bags, and garment panels, so this simple shape opens up an enormous range of projects. Once you can make an even rectangle, you can make most flat things in crochet. For a three sided shape, see how to crochet a triangle, and explore round shapes like the circle.
