If the shade question trips people up, the sizing question trips them up almost as much. You see options like 22, 23, and 24 and there's nothing telling you which one is actually yours.
Here's how I'd think through it.
What the numbers mean
The sizing on acrylic denture teeth mostly comes down to the width of the front teeth as a set, not individual tooth measurements. Smaller numbers mean a narrower, more petite set. Larger numbers mean a wider set built for a bigger mouth and jaw. It's really just a rough matching system, similar to how shoe sizes work off of general foot measurements rather than a perfect custom mold.
Size 22 runs smaller and tends to suit people with a more narrow jaw or smaller mouth overall. Size 23 is the middle ground and it's what most people end up ordering — if I had to guess without any other information, this is where I'd start. Size 24 runs larger and fits a broader jaw or bigger mouth comfortably.
A simple way to check before you order
Look in the mirror and get a sense of your own mouth width, or if you have an old denture or partial that fit reasonably well, that's actually your best reference point. Women more often land in the 22-23 range and men more often in 23-24, but that's a general tendency, not a rule — plenty of people don't fit that pattern at all, so don't force yourself into a size based on that alone.
If you're stuck between two sizes and genuinely can't tell, go with the smaller one. Trimming and adjusting a slightly large fit down is realistic with the tools included in your kit. Going the other direction, trying to stretch a too-small size to fit, is a lot harder and usually doesn't work well.
Something worth knowing before you order
Sizing isn't the same as shade — you'll pick both separately, and they don't affect each other. So don't feel like you need to nail both perfectly on your first guess. Get the shade roughly right and the size roughly right, and the shaping process in your kit does a lot of the fine-tuning for you.
If it doesn't fit once you get there, that's alright — this happens sometimes, and it's usually something we can help sort out. Message us with what you're seeing and we can figure out together whether it's an easy adjustment or worth exchanging for a different size.
