Women’s Underwear Size Guide Chart And Sizing Guide

Women’s undergarments are not made equal, and it can be difficult to determine which one will fit correctly without trying them on first. Wearing a larger size than you need can be uncomfortable and make you look bigger while wearing a smaller size than you need will result in your underwear being too tight and not providing the support you need. If there is a particular brand that you like, then you may already know what size fits best but if this is your first time purchasing panties, a women’s underwear size guide chart can be of great help.

How To Tell What Underwear Size You Are

Brands now are releasing inclusive sizes, meaning they have both regular, plus sizes and another body type. This means that you don’t always have to buy an extra-large or extra small pair of underwear. Instead, you can choose from a range of different sizes from standard sizes to plus sizes. 

It isn’t always easy to tell the right size when buying online or in stores. However, with tips and a size chart, you won’t have to worry about spending money on women’s underwear that doesn’t fit.

Get the tape measure and some underwear that you have laying around. Measure the body measurements such as waist, hips, and thighs while wearing women’s underwear for a more accurate size chart result. Then, check out the women’s underwear size charts below:

Band size is measured across the back of the neck, between the shoulder blades, and along the top of the waistband. It does not include any padding while the cup size is measured from the center of the breastbone down to the bottom of the cups. 

Tip: If you want a tighter fit, start with your underarm pit and measure around it. The measuring tape should be wrapped tightly so that you get an accurate result. This is your “apex” point – the ultimate point of reference from which all other measurements will be measured from. Make sure to place the tape directly on top of your body fat and not on any clothing underneath.

Panty Sizing Chart

Your panties should be snug enough to prevent any panty lines but also allow for movement and ease in fit. No matter the style, they should cover your buttocks completely and leave no skin showing. Size chart for panties works the same way as any other regular size chart such as your pant size chart. You need to measure the waist and hip. 

Here’s a size chart to help you with your purchase.

How to Know If You Have The Right Underwear Size

Knowing how it should feel in your body is a good way to start. Women’s underwear should fit snugly but not too tight; it should be comfortable and supportive.

Butt – Women’s underwear should fit snugly around your butt. Wearing underwear that is too tight can leave red marks around the butt area.

Waist – The waistband should sit comfortably on your waist and not pinch or dig in. Wearing too tight can cause discomfort. Too loose waistband starts to fold over and can cause bunching in your underwear.

Hips – Hips are the widest part of a woman’s body, so underwear that fit well around your hips will be comfortable and look good. The underwear should cover your entire hip area and not be too tight or too loose.

Thighs – The leg holes of the underwear should not be so tight that they dig into your skin; the thigh area should be properly covered. 

Crotch– Women’s underwear should not be too tight or snug in the crotch area. Women’s underwear shouldn’t fit so loose that it moves around when you walk, but it shouldn’t feel like they are cutting off circulation either.

The right women’s underwear size is one that fits your body well and supports all of your curves without feeling too tight or uncomfortable. It should also cover the butt, hips, and thighs for complete coverage throughout your entire body.

If the underwear feels like it is digging into you, then it is probably not the right size. It will end up falling down or riding up when wearing which can cause discomfort and possible rashes or itching. Wrong-sized underwear will not be able to support you properly during wear which can also cause discomfort and possible rashes due to poor coverage in certain areas.

Common Types of Panty Style

Thongs – Women’s underwear that have a narrow strip of fabric that runs between the buttocks and is connected to two wider straps that go around the hips.

Bikini – Women’s underwear with sides that are usually about three inches wide. 

Hipster – These are underwears that sit low on the waist and are designed to provide full coverage in the front and back.

Boyshort – Underwear that is short and fits snugly on the hips. These are similar to men’s boxer briefs, except they have a more feminine cut. 

Lace Panties – These are underwears that have lace detailing on the front, sides, or back.

High Waisted – These are underwear that sits at or above the natural waist and usually covers the belly button. 


Women’s underwear size is a matter of personal preference and comfort, but there are some general guidelines to help you find the perfect fit. Women’s underwear should be snug enough that they don’t fall down or ride up when wearing, but not so tight as to cause discomfort. Women’s panties also need to cover your butt, hips, and thighs for complete coverage throughout your entire body.
