The difference between UK and US crochet stitches

Last year, during a lull in my dressmaking I decided to teach myself how to crochet. Being a visual learner, I turned to YouTube to help me with the stitches. Once I had mastered tension and moved on to different stitches I hit a problem. Different vloggers would give the same stitch a different name. I couldn’t understand why and almost gave up before I had got to grips with my new hobby. Eventually I found the answer. The same stitch has a different name depending on where in the world you live. UK and US crocheters use different terms for exactly the same stitch. So, what is the difference between UK and US crochet stitches?

Triple treble TTR — Double treble DTR


Useful to know

Not all bloggers, vloggers or pattern companies will tell you what terminology they are using. To make it even more confusing some UK vloggers will use US terminology because they are targeting the larger American audience. If looking at the pattern itself doesn’t give you a clue to the stitches used, look for the term ‘single crochet’. The UK doesn’t use have a single crochet stitch so you can be pretty sure it’s an American pattern and translate accordingly.

A useful rule of thumb is that British stitches are one stitch up from their American counterparts. A US single is a UK double. A US double is a UK treble and so on. Another hint is in hook sizes. British hooks are numbered  (eg 5mm hook) whereas the American hooks have letters to determine size.

I hope this helps you to navigate the sometimes confusing difference between UK and US crochet stitches.

Happy hooking!

    It’s absurd isn’t it! One of the most annoying things about crochet! I keep a screen shot of a conversion table on my phone. and don’t get me started on the different names for yarn weights ! Thank you so much for joining us at Handmade Monday.

      I almost stopped teaching myself before I realised why I was getting so confused about the stitches. It should be made clearer which version people are using

    This is very useful Louisa! I’m currently learning to crochet and YouTube is always my go-to place for tutorials.
    I think I need a little more practice at getting the tension right though! I LOVE your blanket. What beautiful colours 🙂

    Thanks so much for sharing with #MMBC. Have a lovely week x

      Thanks Jayne. Tension can be pretty tricky to master, you have to really relax your hand

    Oh dear! I could see how that could get confusing….I didn’t know there was different names for the stitches. How interesting. #MMBC

      It is easy to get muddled if you don’t know there is a difference

    Didn’t even know there was a difference, you learn something new everyday. I wish I could knit, I am useless at it! X #mmbc

      I’d love to be able to knit too!

    I’m trying to learn to crochet, Louisa, so this is really useful! I’m struggling at the moment, in being able to get the tension right, but I’m hoping that it will improve with practise 🙂

      The more you practise the more you will relax and your tension will naturally improve. Maybe try using a bigger hook than your yarn requires and your tension will naturally become loser?

    Es interesante hacer diferencia entre los diferentes términos, yo por eso no sigo gráficos,
    se me hace más complicado el trabajo y siempre tengo cosas fáciles para hacer a mí manera.

    Me alegra coincidir contigo en Handmademonday

      Thank you, the differences can be very confusing can’t they?

    Great reference chart. I guess it depends on if you know what something is supposed to look like too. I was helping someone with an amigurumi question on a crochet board and the directions were from a UK book and not only the stitches were different but the way in which they listed the instructions were slightly different from the way someone in the US would write them. However the stitch count was listed for the end of the round and since many amigurumis follow a basic starting pattern I was able to translate not just the stitches which I knew dc was sc but how to get to 18 stitches at the end of the row with increases which were written in terms I really was not familiar with although I’ve made hundreds of these little animals over the years. All is good the woman was able to continue with her project once she cracked the code.

    In similar fashion when you look at a picture of an item you can for the most part tell if a blanket for instance is using dc or sc stitches. Where it gets tricky is sc and hdc because they can be very hard to the difference if you are trying to decide which stitch the designer wanted.

      I’m so glad that you could help the person struggling with the different terms. I have only made one ami pattern so far and managed it quite well but may have struggled if the terms were different as well as how they gave the instructions.

    Hi Louisa, this post is going to come in handy for UK/US stitch reference as I’ve not done anything other than a double crochet (UK). I should count my blessings that I noticed the difference early on and not when I’d finished crocheting a jumper or something. Saying that, if I hadn’t been crocheting a toy to stuff I probably wouldn’t have batted an eye at the size of the stitches… Love the colourful blanket. The perfect lap warmer on a chilly winters day… Did you get achy in your hands when you started? I’m guessing I’m a little too tense still.

      Hi Debbie. I think it is easy to overlook the differences until you discover your end result is the wrong size or shape.
      The blanket has pride of place in Ps bedroom. It took forever to make but she adores it so it was worth it. I got really sore hands when I first started. I was holding the hook much too tightly and got terrible cramp in my hand as a result. I practised making sure each stitch would slide up and down the hook easily and it helped to lessen my tension. It really is a case of practise makes perfect! xx

    I haven’t crocheted in a few years. I guess I only used US patterns as I never noticed this difference. Confusing if you don’t know the different terms. Thanks for sharing. #MMBC

      It can get really confusing!

    I’ve pinned it. I’ve not encountered the problem, but someone did warn me early on. Probably helps that I’ve only made blankets and cushion covers so far. Flat is very forgiving. I had to note down the yarn terms early on for knitting. This is making me want to break out the hooks and make another blanket. Is that your blanket in the photo? Very cheerful. #MMBC

      Thanks Cheryl. It really does become a problem when making shaped and 3d items and it can get very distorted if you are using the wrong stitches.Yes, it is my blanket, I’ve also recently made a giant granny square into a matching cushion which was very well received!
