Getting the wrong scrub size is more common than you’d think. Studies on healthcare worker comfort show that ill-fitting uniforms directly affect movement, fatigue, and even job performance.
If your scrubs are bunching at the hips or pulling at the shoulders, you’re not alone — and the fix is simpler than you think, especially when shopping IRG scrubs for women.
Should You Size Up or Down?
Size up when your measurements fall between two sizes, or if you move around a lot during your shift. Size down only if a larger size adds so much fabric that it gets in your way.
Most scrub brands use standardized sizing, but fit varies by cut. A straight-leg scrub will feel tighter than a tapered one, even in the same size. So before you default to your usual size, consider the style you’re buying.
The general rule: when in doubt between two sizes, go with the larger one. You can always have scrubs tailored, but you can’t add fabric.
How Do You Measure Yourself at Home?
You need four measurements: bust, waist, hips, and inseam. That’s it.
Here’s how to take each one accurately:
Bust — Wrap the tape around the fullest part of your chest, keeping it parallel to the floor. Don’t pull it tight; you want it snug but not compressing anything.
Waist — Measure around your natural waist, which sits about an inch above your belly button. A lot of people measure too low, which throws off the whole fit.
Hips — Stand with your feet together and measure around the widest part of your hips and seat. For most women, this is about seven to nine inches below the natural waist.
Inseam — Stand straight and measure from your crotch to the floor. This tells you what pant length works for you. Most scrub pants come in petite (about 28–29″), regular (30–31″), and tall (32–34″).
The most important tip: always measure over the type of clothing you’d wear under scrubs — usually a thin layer. Measuring over thick clothes gives you inaccurate numbers.
What If Your Top and Bottom Are Different Sizes?
This happens more than brands like to admit, and it’s completely normal. A lot of women have a smaller top half and fuller hips, or vice versa. The solution is simple — buy separates instead of sets.
Most quality scrub lines sell tops and bottoms individually for exactly this reason. If your bust is a medium and your hips are a large, buy both. Matching them as a set just because they’re “supposed to go together” is what causes that uncomfortable fit in the first place.
Does the Fabric Matter for Sizing?
Yes, and it’s often overlooked. Fabrics with stretch — like those with spandex or elastane blended in — give you more flexibility in sizing. A size medium in a four-way stretch fabric feels very different from a size medium in a rigid cotton-polyester blend.
If you’re choosing a non-stretch fabric, lean toward sizing up by one. If the fabric has built-in stretch, your true-to-size measurement is usually the better call.
According to textile comfort research, healthcare workers who wear well-fitted, breathable fabrics report fewer complaints about physical fatigue during extended shifts. So the fabric-fit combination genuinely matters.
FAQs
How do I know if my scrub top is too small?
If you can see pulling at the chest or the back rides up when you lift your arms, the top is too small. A proper fit lets you raise both arms fully without the hem lifting more than an inch.
Can I shrink scrubs to get a better fit?
Cotton-heavy scrubs will shrink slightly in a hot wash. Synthetic blends generally won’t. Check the care label before you try this — some fabrics shrink unevenly.
What’s the difference between petite and regular scrub sizing?
Petite sizing shortens the torso length and inseam, not just the overall proportions. If you’re under 5’4″, petite scrubs usually give you a cleaner fit without extra tailoring.
Do scrub sizes run small or large?
Most brands run true to size, but unisex cuts tend to run large. If you’re buying from a unisex line, go down one size from your usual women’s size.
How often should you re-measure?
Re-measure every year or whenever your weight changes by more than 10 pounds. Sizes shift, and so do your measurements — staying current saves you from repeat returns. That’s especially useful when ordering IRG scrubs for women online.
