How to get your underwear size right?

Choosing the right size in any clothing can be tricky, but at least with most clothes you can try them before or even after you buy them. But with men’s underwear there is no opportunity to try before you buy. So how to get it right?

We all know that buying your underwear online is a convenient way of shopping and gives you a great range to choose from. But it can be hard to tell from a few photos what the fit is like and what size might be best. Just choosing the size that you normally have does not always work as it can vary with different styles and brands. That’s why we have 100-day worry-free underwear returns. Hint-hint!

But don’t worry our team here at Next Gay Thing are on hands to help point you in right direction. So what do you need to consider when choosing the right size and fit of underwear? Well the areas that you need to consider are:

  • Waist
  • Bum
  • Legs
  • Bulge / package (Or whatever else you might want to call it!)
  • Style
  • Fit
  • Material

We know that seems to be an awful lot to consider, but finding the right size and fit of underwear is important. As poorly fitting underwear can be uncomfortable and even painful.

So let’s give you the lowdown on each of those areas.


This is where most people start when considering what size to choose. Which makes sense as pretty much all men’s underwear is based on the waist size. The most basic rule here is there is no point trying to squeeze your 36 inch waist into a 28 inch waist pair of briefs. That’s why we decided to add a size guide for each brand in our store. 

But because most waists have an elasticated waistband you may consider going up or down a size if it’s going to help the fit somewhere else. For example you may normally be a 30 inch waist, but you find a 30 inch doesn’t give you enough room for your manhood. But the rule here is that they shouldn’t be too tight or falling down. 


Making sure you get the fit on the bum right will depend on 3 factors. The first being the style of underwear. If you choose jocks then it becomes less of an issue as your cheeks are hanging out. Second is the cut of the underwear, if you choose a brief then a low rise cut would tend to cut higher on the bum. Finally the size and shape of your bum. If you have a larger bum that’s a bit flabby you need to watch out for your underwear pinching too much under your cheeks. If you have a very small bum then you might find that your undies are a bit saggy.


This one really comes down to the size of your legs and in particular your thighs. Are you sporting a rugby player pair of legs or do you have legs the size of a sparrow? First of all make sure they are not too tight and cutting into your legs. Briefs that are too tight will cut into your groin, but if they are too lose then you will be falling out the sides. If you struggle to find any underwear that is too tight on your legs you could consider boxers. For example like these boxers from Hunk or PUMP! underwear.

Most material now has a fair amount of stretch in it, but if you’re struggling with something to fit your legs then look for something with a higher amount of spandex.


So this one gets a bit tricky getting your underwear in fit in this area is down to a couple of things. First of all if you’re wearing loose underwear like traditional boxer shorts then it’s not really going to be an issue as you will just hang free, but then you’re missing the support that more form fitting underwear can provide. The question is do you go for a pouch or not, if you don’t then you might to be squashed flat, which is fine if you struggle find a pouch that fits your package. If you go for the pouch but it’s too small you will get a gap where the material should be flush against your groin. Different styles and brands have different sizes of pouch so that can help you get the right fit. Recently, our customers really liked the underwear from ADDICTED

Briefs from ADDICTED – second skin navy. They have big pouch for best comfort. 

Jocks from ADDICTED – firstly, this color is just a bomb! Secondly, they have a removable COCK RING. It’s always fun to try something new!


The style of underwear that you choose will have a big impact on the size that you need to select. For example if you choose boxer shorts then it’s the waist size that’s most important. If you were going for briefs then you need to think about the waist size, but also consider the bum, legs and bulge areas, which may make you think about going up or down a waist size. If you are going for a jocks then you don’t need to worry about coverage on your bum, but you will need to think about the waist and the bulge.


The cut of your underwear may also be a factor. If you go for a low rise pair of briefs or trunks it may change what waist size you go for as they will possibly be a bit on the tighter side or have less coverage. So if your bum is a bit on the bigger side you probably want a brief that has a lower cut on the rear to give you more coverage. In our store you can find underwear that will fit you perfectly or just create your taste profile and choose your Gay Pack and our team will take care of your underwear. We also have a Gay Pack with only underwear – the Bare pack – you can check it here.


Material can also make a difference as some materials may have more give or stretch in them than others. So underwear that has a high degree of cotton without much spandex in would most probably not give as much as something that had a high content of spandex. We can recommend you try try mesh underwear. If you not sure that this material is practical you can check our article Is mesh underwear practical. Also material that is thicker is less likely to stretch. 

Hope this information will help you to choose the best underwear. If you have more questions than we are always happy to help you. Just get in touch and we’ll take it from there!
