That depends on a few different factors. It's worth considering your body type, where you plan to wear the jeans, and what kinds of styles you prefer.
For instance, if you have an athletic build, you may want to look for jeans that are made of more flexible material so they'll fit more comfortably around your thigh and calf muscles. On the flip side, if you have a very curvaceous body type, you might be better suited to a tailored fit with a bit more room throughout.
Your lifestyle also matters when it comes to finding the right size jeans for you. For instance, if you're constantly on the go and plan to wear them for active use, you'll want to look for something with a bit more stretch or a looser fit. On the other hand, if you plan to wear them for a more formal occasion, you'll likely want something with a more polished silhouette.
Finally, it's important to think about the style of jeans you prefer. Do you like slim fits, mid-rises, and cropped fits? Once you have all these factors narrowed down, it will be much easier to figure out the size of jeans that will best fit you.
If you're still unsure about what size to get, you can always use size guides, like this one here: https://www.levi.com/US/en_US/help/men/jeans-sizing-guide.
