I'm 5'5" and bought a size medium. They are kind of big and slide a little. If they stretch out, they won't fit at all.
I think a small would have been a better fit. I plan to buy another pair. The are really great gloves! I've owned many brands, and I really like Cathe's
I bought the fitness gloves. I wear a size 6 glove and the small went on but I thought it felt tight. I returned them and got a size medium. They go on much easier and I like them.
I don't think glove size has all that much to do with your height.
I asked Cathe about the fit, and she said that they tend to run small and she wears the medium (she's either 5' or 5'2", I forget).
The weighted gloves are a one-size-fits-all style.
