It really depends on the specific fit and style of the jeans you’re looking at since with denim there’s no universal sizing standard across brands. However, in general, H&M jeans tend to be true to size, if not slightly bigger.
When shopping for H&M jeans specifically, here are some tips to keep in mind:
• Check out the size guide on their website and even print it out to make sure you get the right sizing - a lot of people find this helpful.

• Consider ordering two sizes - within H&M’s return policy - if you’re unsure of sizing. You can return the item that does not fit without any hassle.
• Try and buy in-store if you can. This way you can try on different sizes and see what fits best on you.
• Pay attention to the ‘Fit’ listed and described in the product details. Different fits may affect the sizing e.g. skinny, regular, or high waist jeans may all fit differently.
• Try to look at customer reviews and see how true to size it is for other people.
Hope this helps!
