Hmm I had a measuring thing in my sewing kit but I don't know where it is right now. I'll have to see if I can find it. I got pants ranging from size 1-5. Women's belt size I usually get small or medium and make extra loops if need be haha. 

 Oooh, you're a woman? Yeah.. sizes are confusing probably even more so for woman. Size 1 to 5 is a ridiculous way to size them imo 😂.

If you have a belt you already use, the best way to know is do this.

 Oh! I have an old belt I can measure I'll do that this weekend. 

 Measure the width too!
