Clavicular Gear Sizing Guide: How to Get the Perfect Fit 2026

Stop guessing your size. This Clavicular gear sizing guide shows you how to measure for t-shirts, hoodies, leggings, and shorts so your gear supports your workout, not hinders it.

Why Proper Sizing Matters for Workout Performance

Getting the right size in your workout gear isn't just about looking good. It affects every rep, every mile, every stretch. A shirt that is too loose can catch on equipment or ride up during a deadlift. Shorts that are too tight restrict your range of motion in a deep squat. In my 10 years working with print-on-demand and merch design, I have seen countless people ruin a perfectly good training session because their clothes fought against them.

This Clavicular gear sizing guide will teach you how to measure yourself accurately and use the size chart to choose the best fit for your body and your activity. By the end, you will know exactly which size to order for t-shirts, hoodies, leggings, and shorts. You will also learn the most common mistakes that lead to returns and how to avoid them.

How to Measure Your Chest, Waist, and Inseam

Before you look at any size chart, you need your own measurements. Use a soft measuring tape. Wear little or no clothing when measuring. Stand straight but relaxed.

Step 1: Chest/Bust

Wrap the tape around the fullest part of your chest, just under your armpits. Keep the tape horizontal and snug but not tight. Breathe normally. Write down the number in inches.

Step 2: Waist

Measure around your natural waistline, which is usually just above your belly button. If you wear your pants lower, also measure at that point. This matters for shorts and leggings.

Step 3: Inseam

For bottoms, the inseam is key. Measure from the top of your inner thigh down to where you want the hem to end. For shorts, 5-7 inches is common. For leggings, measure the full length to your ankle.

Step 4: Hips

For leggings and shorts, also measure the widest part of your hips and glutes. This prevents that over-stretched look.

Pro tip: Have a friend help you with back measurements. A mirror works, but it is less accurate. Measure twice and take the larger number if there is a difference.

Clavicular Sizing Chart for T-Shirts and Hoodies

Below are the general sizing ranges for Clavicular tops. Note that individual products may vary by 0.5-1 inch due to fabric and cut. Always check the product page for the specific size chart.

T-Shirts (Chest Width, inches)

XS: 34-36
S: 36-38
M: 38-41
L: 41-44
XL: 44-47
2XL: 47-50
3XL: 50-53

Hoodies (Chest Width, inches)

XS: 36-38
S: 38-40
M: 40-43
L: 43-46
XL: 46-49
2XL: 49-52
3XL: 52-55

Hoodies typically have more room in the chest and shoulders to allow layering. If you wear a Large in t-shirts, you may prefer a Medium in hoodies for a closer fit. For a relaxed look, stick with your usual size.

Pro tip for shrinkage

Most Clavicular shirts are 100% cotton or cotton-poly blends. They may shrink 2-3% in the first wash. If you are between sizes, order the larger size and wash on cold, then tumble dry low.

Finding the Right Fit for Leggings and Shorts

Bottoms require more care because they interact with your movement directly. A poor fit here means constant adjusting.

Leggings

Clavicular leggings use a 4-way stretch fabric. Measure your waist and hips. The waistband should sit flat without rolling. If you have a gap at the back, you need a smaller waist size or a curvy cut. The inseam for full-length leggings is typically 28-30 inches. For 7/8 length, it is 24-26 inches. Check the product description for the exact inseam.

Shorts

Clavicular training shorts come with a 7-inch or 5-inch inseam. The waistband should be snug enough to hold the shorts up without a drawstring, but not dig in. Measure your waist at the level you wear shorts. If you are between sizes, choose the larger size because you can always tighten the drawstring.

Common mistake: Buying shorts based on pant size. Shorts sit higher than jeans. Always measure.

Tips for International Buyers (Metric Conversions)

If you are ordering from outside the US, use a metric tape. Here are the conversions you need.

1 inch = 2.54 centimeters
Chest 34 inches = 86 cm
Waist 30 inches = 76 cm
Inseam 28 inches = 71 cm

Clavicular gear is designed with US sizing. Do not assume your usual European or Asian size will match. For example, a US Medium is often a European Large. Check the chart on the product page carefully.

I recommend adding 1-2 cm to your measurement for breathing room, especially for tops. When in doubt, contact us through our Contact page. Do not guess.

Common Sizing Mistakes to Avoid

Using old measurements. If you have lost or gained weight since the last time you ordered, remeasure. Bodies change.
Choosing based on label only. Two different products from the same brand can fit differently. A relaxed-fit tee will be roomier than a performance-fit tee even in the same size.
Ignoring the fabric. Cotton shrinks. Polyester doesn't. If the shirt is 100% cotton, account for shrinkage.
Not reading the product description. Some Clavicular items are intentionally oversized. The product page will say. Don't assume.
Relying on your usual size from another brand. Brand sizing is not standardized. Always use the specific chart.

Frequently Asked Questions

How do I know if I am a Small or Medium?

Measure your chest and compare to the chart. If your chest is 37 inches, you are between S and M on the t-shirt chart. For a tighter fit, choose S. For a standard fit, choose M.

Do Clavicular leggings have a gusset?

Yes, all Clavicular leggings have a cotton-lined gusset for comfort and hygiene. This does not affect sizing, but it does add a small amount of fabric in the crotch area.

What if my waist measurement says one size but my hips say another?

Size for your hips. Leggings need to accommodate your glutes. You can always cinch the waistband tighter with the drawstring if there is one.

How do I wash my new gear to avoid shrinking?

Wash in cold water and tumble dry on low heat. Air drying is even better. Avoid hot water and high heat.

Can I exchange if the size is wrong?
