How to crochet in the round and keep it flat

When crocheting in the round it is important to know the basics.  You’ll want your blankets or loveys to stay flat, right?

Or even when you want to start making Amigurumi’s, it is important to know the basic principles of crocheting in the round first.


To keep it flat, you’ll have to do some very simple math. First you’ll need a reference stitch.  I always use single crochet, because for me this works best.

I choose the 3 most basic crochet stitches to show you how this technique works, but as long as you use your reference stitch to make your calculations, you can use any stitch!

To calculate the proportions of a stitch, you’ll need to make a swatch first.  Next you’ll compare the stitch count of this swatch, with your swatch of single crochet stitches.   It’s getting a bit blurry before your eyes?  Don’t worry, I’ll explain it all to you in the next three points.

Now… I can hear you think: “Yeah… but on your photo’s the circles clearly aren’t flat.”  That’s right.  But I purposefully didn’t block my swatches to show you how it looks before blocking.  You’ve noticed that the edge is curling up a bit and that’s great!  But no worries, every next round you’ll crochet, it will straighten out.  And after blocking, you’ll have the perfect flat circle.

Problem solving

Everyone has a bit a different tension or a different stitch definition.  Also every yarn crochets a bit different, as well as the hook you’re using.

If you notice that, despite the basic rules, your work curls up or gets wobbly, you might want to change your crochet hook.


My work gets wobbly

This means that your stitches are to big.  I recommend going down 1/2 of 1 size for your crochet hook or to use a hook made from an other material.

My work curls up

If this happens, your stitches are to small.  Also in this case, I recommend switching your crochet hook.  You can either go for a bigger hook or a hook in another material.

Used materials

I used Drops Paris for this blogpost and a 5 mm Clover Amour crochet hook.

To determine which size hook to use, just check the label on your yarn.  Most of the time you’ll find a symbol of a crochet hook on it, with a number besides it.  That number indicates the size hook is recommended to use.


mr = magic ring
sc = single crochet
hdc = half double crochet
dc = double crochet
inc = increase by making 2 stitches in the same stich
dec = decrease by crocheting the next 2 stitches together

(…) x times = repeat what’s between brackets the number of times mentioned (or until the end of your round)
(number) = the number between brackets, indicates the number of stitches you should have at the end of your round.

How to crochet in the round and keep it flat with single crochet

Increase 6 stitches every round, if you’re using single crochet.  If you like your circle to be perfectly round, you’ll want to space the increases evenly, but every round on a different place.  If you increase on the same spot every round, you’ll end up with a hexagon.  This doesn’t really matter, if you’re making amigurumis, but if  might if you’re making a blanket or a lovey.


This is just an example.  You can increase where ever you like in every round, as long as your increases are spaced evenly.

  1. make 6 sc in a mr (6)
  2. (inc) x6 (12)
  3. (1 sc, inc) x6 (18)
  4. (inc, 2 sc) x6 (24)
  5. (3 sc, inc) x6 (30)
  6. (2 sc, inc, 2 sc) x6 (36)
  7. (inc, 5 sc) x6 (42)
  8. (4 sc, inc, 2 sc) x6 (48)
  9. (1 sc, inc, 6 sc) x6 (54)
  10. (5 sc, inc, 3 sc) x6 (60)

That’s how it works!  If you like to add rounds to your circle to make it bigger, just keep increasing 6 stitches every round.



How to crochet in the round and keep it flat with half double crochet

The half double crochet stitch is about 1,5 times the size of a single crochet stitch.  You just learned that you need to start with 6 stitches to keep your circle of single crochet flat.  This means that for a half double crochet circle, you’ll need to increase 1,5 times more.

6 x 1,5 = 9 stitches

So let’s make 9 half double crochet in a magic ring. Next we’re gonna increase 9 stitches every round.  Also make sure to space the increases evenly this time.


  1. make 9 hdc in a mr (9)
  2. (inc) x9 (18)
  3. (1 hdc, inc) x9 (27)
  4. (inc, 2 hdc) x9 (36)
  5. (3 hdc, inc) x9 (45)
  6. (2 hdc, inc, 2 hdc) x9 (54)

If you like to make it bigger, just keep adding those 9 increases every round.



How to crochet in the round and keep it flat with double crochet

A double crochet is about 2 times bigger than a single crochet.  If we use the same calculation-trick, that we used before, this means:

6 x 2 = 12 stitches

So this time you start with 12 double crochet stitches in a magic ring. Next we’re gonna increase 12 stitches every round, spaced evenly.


  1. make 12 dc in a mr (12)
  2. (inc) x12 (24)
  3. (1 dc, inc) x12 (36)
  4. (inc, 2 dc) x12 (48)
  5. (3 dc, inc) x12 (60)

Want to make it bigger?  Just keep increasing 12 double crochet stitches every round.

Congratulations!  You’ve just learned the basics on how to crochet in the round and keep it flat!

Now that you know this, you can start experimenting with different kinds off stitches.  Mix and match to make a gorgeous round baby blanket.  Make sure to make a swap first and compare it with your single crochet swap, to make your calculations.

I am really curious about all the beautiful things you guys are going to create! Let’s get crocheting in the round.

crafty greetings,

    • Dank je wel. Ik hoop dat ik hier veel (beginnende) hakers een plezier mee kan doen. Ik heb er vroeger zelf enorm veel aan gehad. 😉
