Ever ordered a 3XL from one brand and a 4XL from another, only to discover that neither fits the way you expected? You're definitely not alone.
Plus-size clothing can vary quite a bit from one brand to another. A 4XL isn't necessarily the same size everywhere, which is why relying on the label alone can sometimes lead to disappointing fits.
The easiest way to avoid the guesswork? Know your measurements.
At XMEX, we create clothing specifically for sizes 3XL through 7XL, and we want you to feel confident about your fit before you place an order. Measuring yourself at home takes only a few minutes, and once you know your numbers, shopping for the right size becomes much easier.
Here's everything you need to know.
What You'll Need
You don't need anything complicated. Just grab:
-
A flexible measuring tape, like the ones used by tailors
-
A mirror or someone who can help you measure
-
A well-fitting T-shirt or thin top
-
A pen and paper or your phone to record your measurements
Try to measure over light clothing or directly over your clothes rather than wearing anything bulky.
The 4 Measurements That Matter Most
1. Chest / Bust
Wrap the measuring tape around the fullest part of your chest or bust. Keep the tape straight and parallel to the floor all the way around your body.
It should feel comfortably snug, but don't pull it so tightly that it digs into your skin.
A helpful tip: Keep your arms relaxed at your sides and breathe normally while measuring. There's no need to hold your breath or puff out your chest.
2. Waist
For your waist measurement, find your natural waistline. This is generally the narrowest part of your torso and is often around an inch above your belly button.
Wrap the tape around your waist without sucking in your stomach. Let your body stay relaxed and natural.
Not sure where your natural waist is? Try bending slightly to one side. The crease that forms is usually a good indication of where your natural waistline sits.
3. Hips
Stand naturally with your feet together and wrap the tape around the fullest part of your hips and glutes.
For many people, this point sits roughly 7–9 inches below the waist, although everyone's body shape is different.
Make sure the tape stays level as it goes around your body. It's surprisingly easy for the tape to rise or dip at the back without you noticing.
A mirror can make a big difference here.
4. Sleeve Length
If you're buying shirts, sleeve length is another measurement worth knowing.
Start at the center back of your neck. Measure across your shoulder, then continue down the outside of your arm until you reach your wrist bone.
Keep your arm slightly bent rather than holding it completely straight. This gives you a more natural measurement that better reflects how the sleeve will sit when you wear the shirt.
What Do You Do With Your Measurements?
Once you've written down your measurements, compare them with the size chart on the specific XMEX product you're interested in.
This step is important because different styles can have slightly different cuts. A formal shirt, T-shirt, and sportswear piece may not fit exactly the same way, even when they're marked with the same size.
So rather than thinking, "I normally wear 4XL," think, "These are my measurements, and here's what the size chart recommends."
That's a much more reliable way to choose your size.
What If You're Between Two Sizes?
If your measurements fall between two sizes, consider how you like your clothes to fit.
-
Prefer a relaxed, comfortable fit? Generally, size up.
-
Prefer a closer, more fitted look? You may be able to size down, provided you're only slightly between sizes and the garment's cut allows for it.
-
Buying stretch fabric? Your actual body measurements can usually be used more directly when choosing your size.
When in doubt, always give the individual product's size chart priority.
Common Measuring Mistakes to Avoid
Getting accurate measurements isn't difficult, but a few small mistakes can throw everything off.
Measuring over bulky clothing
A hoodie or thick sweater can add several inches to your measurements. For the most accurate results, wear a thin T-shirt or measure directly over light clothing.
Pulling the tape too tight
The goal isn't to see how small you can make the measurement. The tape should sit comfortably against your body without squeezing.
Letting the tape sag
This is particularly common when measuring your chest or hips. Use a mirror to make sure the tape stays level all the way around.
Measuring completely by yourself
You can absolutely measure yourself, but having someone help can make the process much easier and more accurate, especially when measuring your back, shoulders, or sleeve length.
Using measurements from months ago
Your body can change over time, even if your weight hasn't changed dramatically. It's a good idea to recheck your measurements every 6–12 months, especially before ordering from a new brand or trying a different type of clothing.
Why Accurate Measurements Make Such a Difference
Getting your measurements right isn't just about choosing the right number on a size chart.
It's about finding clothes that look better, feel better, and give you the confidence to wear them comfortably.
Accurate measurements can also mean fewer exchanges, fewer returns, and less frustration when shopping online.
That's what we're aiming for at XMEX: making it easier to find clothes that fit real bodies properly, from 3XL all the way through 7XL, without having to guess.
