How to Crochet a Perfect Circle (From Hexagon To Circle)

Share This Pattern :

If you have been crocheting flat circles and ending up with something that looks more like a stop sign than a circle, this post is exactly what you need. This is one of the most common frustrations beginners run into, and the good news is the fix is incredibly simple, it comes down to one small change in your pattern. In this post I am going to walk you through why it happens, how to fix it, and give you the exact pattern for a perfect circle every single time, so without further ado let’s get into it!

Why Your Crochet Circle Has Corners

Most beginner circle patterns are written like this:

Rnd 1: MR, 6 SC. (6)
Rnd 2: (INC) x6. (12)
Rnd 3: (INC, SC) x6. (18)
Rnd 4: (INC, SC 2) x6. (24)
Rnd 5: (INC, SC 3) x6. (30)
Rnd 6: (INC, SC 4) x6. (36)

Notice how the increase always comes first in every single repeat? That means your 6 increases land in the exact same 6 spots every round, stacking directly on top of each other like little pillars. Those stacked increases push upward and outward and create 6 raised corners. That is your hexagon right there, and it is not a tension problem, it is not your hook size, it is simply the way the pattern is written.

The Perfect Circle Pattern

The trick is to shift where your increase sits within the repeat so the increases never pile up in the same spot. Here is the corrected pattern:

Rnd 1: MR, 6 SC. (6)
Rnd 2: (INC) x6. (12)
Rnd 3: (INC, SC) x6. (18)
Rnd 4: (SC, INC, SC) x6. (24)
Rnd 5: (INC, SC 3) x6. (30)
Rnd 6: (SC 2, INC, SC 2) x6. (36)
Rnd 7: (INC, SC 5) x6. (42)
Rnd 8: (SC 3, INC, SC 3) x6. (48)

The increase alternates between sitting at the start of the repeat and being sandwiched in the middle. Because the increases never stack, no corners form, just a smooth, even curve all the way around.

Note: Both patterns produce the exact same stitch count every round. The only difference is where the increase sits within the repeat. Same numbers, completely different result.

Why Is My Crochet Circle Curling Up?

If your circle is cupping upward instead of lying flat, there are two possible causes.

The first is tight tension. Your stitches are pulling the fabric inward and forcing it to curl. The fix is simple, go up one hook size without changing your yarn. You do not need to recount or rework your pattern, just give your stitches a little more room and the circle will relax flat on its own.

The second cause is too many stitches. If you have added an extra increase somewhere without realizing it, the extra fabric will start to curl upward before it gets dramatic enough to ruffle. Count your stitches at the end of each round, a flat circle grows by exactly 6 stitches per round, so your counts should always follow 6, 12, 18, 24, 30, 36. If you are over, you have a sneaky extra increase hiding somewhere.

Tip: If your circle starts flat and then begins to curl after a few rounds, that points to a stitch count problem. If it curled from the very beginning, it is almost certainly tension.

Tip: Place a stitch marker at the start of each round and count before you move on. It takes 10 seconds and saves you from frogging the whole thing.

Why Does My Crochet Circle Have a Bump or Hole in the Center?

This comes down to how you started your circle. There are two common methods, a chain ring and a magic ring, and they behave very differently.

If you started with a chain ring (chaining 4 or 6 and joining with a slip stitch), you will almost always have a small visible hole in the center. That is just what chain rings do, and for some projects like granny squares it does not matter. But for a clean flat circle it is not ideal.

If you started with a magic ring and still have a hole, it means you did not pull the tail tight enough after your first round. Go back, pull the yarn tail firmly before you slip stitch to close round 1, and the hole will close up completely.

If you have a bump or raised knot in the center, it is usually a loose yarn tail that was not woven in properly. Weave it in again more carefully through several stitches in different directions.

Why Does My Crochet Circle Look Uneven or Lopsided?

An uneven circle usually means your stitch count drifted at some point, you either added or skipped a stitch without noticing, which throws the spacing of your increases off balance. Once the increases are unevenly spaced, every round after that will look slightly off.

The best way to prevent this is to count at the end of every single round, especially in the first 4 rounds where the circle is still small and mistakes are easiest to miss. If you catch a mistake within a round or two, it is worth frogging back to fix it. If you catch it much later, honestly? Start over, a lopsided base only gets more obvious as the piece grows.

Extra Tips for a Rounder Circle

Work in a continuous spiral. Joining with a slip stitch and chaining up at the end of each round creates a small jog that can make corners more visible. Working in a continuous spiral naturally distributes your stitches more evenly and keeps everything smooth.

Keep an even tension. Tight tension will not cause corners on its own, but it can make existing corners look more pronounced. A relaxed, even tension lets the circle lie flat and the edges stay tidy.

Frequently Asked Questions

Why does my crochet circle curl upward?
Curling is almost always a tension issue, your stitches are too tight. Try going up one hook size and see if that helps it lie flat, but sometimes it could be a count issue, adding more stiches will absolutely curl your circle.

Why does my crochet circle ruffle at the edges?
Ruffling means there are too many stitches in the round. This usually happens from miscounting or adding increases too frequently. Count your stitches at the end of each round to catch this early.

What projects use flat crochet circles?
Coasters, bag bases, amigurumi heads and bodies, mandalas, rugs, wall hangings, and appliqués all start with a flat crochet circle , so getting this right opens up a huge range of projects!
