Modern Wisdom Merch Sizing Guide: Find Your Perfect Fit

Finding the right size in a t-shirt or hoodie is about more than just picking a letter. It’s about matching the garment to your body, your style, and the way you live. If you’re part of the Modern Wisdom community, you already know we care about the details - and that includes how our merch fits. This guide is built to help you measure, convert, and choose with confidence.

How Modern Wisdom T-Shirts Fit

Modern Wisdom t-shirts are designed with a regular, but not baggy, fit in mind. They sit close enough to follow your natural line, but they give you room to move without feeling restricted. The fabric is a medium-weight combed cotton with a touch of stretch, which helps the shirt keep its shape through repeated washes and daily wear.

Most fans agree that the t-shirts run true to size. If you prefer a looser, more relaxed look, sizing up is a safe move. If you like a sharper, slimmer silhouette, stick with your normal size. For those in the community who train hard and carry extra muscle in the chest and shoulders, we recommend checking your chest measurement before ordering - a size regular may hug a little too tightly.

One thing you don’t have to worry about is dramatic shrinkage. The tees are pre-shrunk, so you can wash them in cold water and dry on low without the fit suddenly changing. That’s a small thing, but it goes a long way toward making sure your gear feels the same months down the road.

Hoodie Sizing and Comfort

Hoodies are a different beast. They’re built to be comfortable, but that doesn’t mean oversized. The Modern Wisdom hoodie uses a heavier fleece with a soft brushed interior. The fit is relaxed through the body, which gives you room for layering, but the cuffs and hem are ribbed to keep the warmth in and prevent bunching.

In terms of sizing, the hoodie is a bit more forgiving than the t-shirt. If you’re planning to wear it over no more than a t-shirt, your usual size should work well. If you like to layer over a thick flannel or want an extra-cozy feel, sizing up gives you that without making the shoulders look sloppy. The heavier fabric has a bit of drape, so a size up still looks intentional.

If you’re between sizes, here’s the rule of thumb: go down for a trimmer look, go up for a cozier one. The hoodie’s stretch and relaxed fit mean you have more leeway than with a tee.

How to Accurately Measure Yourself

The most reliable way to find your size is to measure your body and compare it to the size chart on the product page. It takes two minutes and removes all guesswork. Here’s how to do it right.

Use a flexible measuring tape. For your chest, wrap it around the fullest part of your chest and shoulder blades, keeping the tape level. For your waist, measure at your natural waistline - that’s the narrowest part of your torso. For the length, start at the top of your shoulder and measure down to the point where you want the hem to sit.

Once you have those numbers, you can translate them into a size. To give you a reference, here’s a typical US size chart for unisex apparel like ours:

These numbers are a starting point. The actual measurements on each product can vary, so always check the specific size chart listed on the product page before finalizing your order.

International Size Conversions Explained

Modern Wisdom merch uses US sizing, and that can be a bit confusing if you’re used to a different system. Here’s a quick breakdown to make international ordering simple.

For UK and Australia, the letter sizes are essentially the same as the US. A US Medium is a UK Medium, and the same goes for Australia. If you shop in those countries, you can pick your usual letter and be confident.

For Europe, things shift to numeric sizing. Instead of S, M, L, European manufacturers often use numbers like 46, 48, 50, and 52. As a general guide, US S maps to EU 46, US M to EU 48, US L to EU 50, and US XL to EU 52. These numbers correspond to the chest circumference in centimeters on the halfway point of the range.

Here’s a simple table to help you visualize it:

Keep in mind that these are approximate. If you’re right on the edge of two sizes, it’s always safer to go with the larger one for more room, or the smaller one for a tighter fit - it depends on the look you’re after.

Common Sizing Questions from Fans

I’m between sizes - should I size up or down? For t-shirts, sizing down gives you a slimmer silhouette, while sizing up adds a relaxed, casual vibe. For hoodies, sizing up is the safer choice if you plan to layer. If you’re still unsure, compare your chest measurement to the size chart and see which range you fall into.

Will the merch shrink after washing? Most Modern Wisdom pieces are pre-shrunk, so you don’t have to worry about dramatic changes. To keep the fit and fabric in top condition, wash cold and tumble dry low. That’s the best way to preserve the garment’s shape.

I have a bigger chest and shoulders because I lift. Which size should I pick? If you carry more muscle in the upper body, focus on the chest measurement rather than your usual letter. A size up often works better because it gives you extra room in the shoulders without making the waist too baggy. That’s the sweet spot for a built-in fit.

Ready to Find Your Fit

Once you have your measurements and know how you like your gear to fit, you’re all set to grab what you need. We think the best way to find the right size is to measure first and trust the numbers. That’s the boring, reliable method - and it beats guessing yourself into a return.

So go ahead, measure once, and then pick the piece that’s going to look and feel right. When you’re ready to rep the podcast, visit the Modern Wisdom store and grab your size.
