T-Shirt Size Guide: How to Measure & Pick the Perfect Fit

Finding the perfect t-shirt isn't just about picking your favorite color or print — it starts with getting the right fit. Whether you’re after a relaxed streetwear vibe, a slim tailored look, or something in between, choosing the right t-shirt size makes all the difference. A well-fitted tee feels better, looks sharper, and gives you confidence from the inside out.

In this ultimate T-Shirt Size Guide, we’ll show you exactly how to measure your t-shirt, compare fits across Raccsy’s signature styles, and pick the size that works best for your body and style preferences. Let’s get it right from the first wear.

Why T-Shirt Fit Matters (and How to Get It Right)

Why T-Shirt Fit Matters?

Getting the right t-shirt fit isn’t just about comfort—it’s about style, confidence, and movement. The way your shirt fits affects how it pairs with other clothing, how it falls on your body, and how it holds up over time.

From fitted cuts that hug the body to oversized silhouettes made for layering, each style has its own vibe and function. Raccsy offers multiple signature styles, each with a unique fit profile, so you can match your t-shirt to your mood, occasion, or aesthetic.

Understanding the importance of t-shirt size is the first step toward looking and feeling your best.

How to Measure Your T-Shirt (Flat-Lay Method)

The most reliable way to find your perfect t-shirt size? Measure a t-shirt you already love — one that fits the way you want.

Follow this simple method:

What You’ll Need

• A flat surface (like a table or clean floor)

• A soft measuring tape or ruler

• A t-shirt that fits you well

Step-by-Step Instructions

1. Lay the Shirt Flat

Smooth it out gently — remove any wrinkles without stretching the fabric.

2. Measure the Chest Width

Measure across the chest from armpit to armpit.
👉 This is often called the “body width.”

3. Measure the Body Length

Measure from the top of the shoulder (near the collar) straight down to the bottom hem.

4. Optional: Measure the Sleeve Length

Measure from the shoulder seam to the sleeve end for long or short sleeve fits.

💡 Tip: Always double-check your measurements. A ½ inch can make a big difference in how your shirt fits — especially in slim or oversized styles.

Compare Your Measurements with Our Size Chart

Now that you’ve taken your measurements, it’s time to match them to the right size.

Every Raccsy tee comes with its own unique size chart depending on fit style — from standard to oversized.

Here’s a quick breakdown:

T-Shirt Style	Fit Type	Sizing Advice
Jersey Tee	Standard Fit	True to size
Oversized Tee	Oversized Fit	Roomy by design – size down for slimmer look
Unisex Tee	Relaxed Fit	Slightly looser than standard
Mineral Wash Tee	Boxy Retro Fit	Wider body, shorter length – ideal for streetwear
Tie-Dye Tee	Loose Fit	Slightly larger due to dye process
Ringer Tee	Slim/Retro Fit	Snug fit – size up if in doubt

Next Step: Compare your chest and length measurements with the chart on the product page. For example:

Size	Chest Width (in)	Body Length (in)
S	18	28
M	20	29
L	22	30
XL	24	31

Pro Tip: Still unsure? Choose the larger size if you’re in between. You can always crop or style oversized — but too small is harder to fix.

Fit Tips and Styling Suggestions

1. Want a more fitted look?

If you prefer your tees to have a slimmer, more tailored fit, consider sizing down when choosing oversized or unisex styles. This helps reduce excess fabric and creates a cleaner silhouette without sacrificing comfort.

2. Looking for a relaxed, baggy streetwear vibe?

For that cool, casual, and roomy feel, size up by 1 or 2 sizes. This will give you extra space around the shoulders and body, perfect for layering over hoodies or pairing with wide-leg pants.

3. Cotton care to keep your fit perfect:

Since these tees are made from 100% cotton, they may shrink a bit after washing. To minimize shrinkage and maintain the shirt’s original size and shape, always:

• Wash in cold water with similar colors
• Avoid using a dryer—hang dry your shirt instead to preserve the fabric and fit

4. Styling ideas to complete your look:

Elevate your streetwear outfit by pairing your tie-dye or mineral wash tee with:

• Joggers for sporty comfort
• Cargo pants for that utilitarian edge
• Raccsy's oversized hoodies for extra warmth and a layered aesthetic

T-Shirt Sizing Tips: Before You Checkout

Compare with a favorite shirt

Take one of your current t-shirts that fits you well and lay it flat. Measure key areas like chest width, sleeve length, and overall length, then compare those measurements to our size chart. This helps ensure you pick the size that matches your style and fit preferences.

Measure carefully—don’t guess your size

Use a measuring tape to measure your shirt or your body accurately. Avoid estimating or relying solely on typical sizes like S, M, L, since sizing can vary between brands and styles.

Read the product page thoroughly

Check for any specific fit notes or fabric details that might affect sizing, such as shrinkage, stretchiness, or how the cut runs (e.g., slim, oversized). These insights help you choose the perfect size with confidence.

FAQ – T-Shirt Sizing & Fit Guide

How do I know which Raccsy t-shirt fit is right for me?

Use your own measurements and compare them with our charts. Decide based on whether you want a tighter, standard, or oversized fit.

Should I size up for an oversized look?

Yes! If you want a more relaxed or baggy streetwear look, size up by 1–2 sizes depending on your style preference.

Will these t-shirts shrink after washing?

Most of our tees are pre-shrunk or shrink-washed, but 100% cotton shirts can shrink slightly. Always wash in cold water and hang dry to maintain fit.

I’m between two sizes. What should I do?

Choose the larger size for a roomier feel or the smaller one for a closer fit. You can also contact our team for personalized advice.

Can I use body measurements instead of a shirt?

Yes, but measuring a shirt you already like usually gives more accurate results. If using body measurements, ensure the tape isn’t too tight.

Do your size charts apply to all styles?

Each style has its own fit and size chart. Always refer to the size chart on the specific product page.
