What size should I get if I'm between sizes on the AMP size chart?

For t-shirts, size down for a slim fit or up for relaxed. For hoodies, always size up - the boxy cut accommodates the larger size better. Use your chest measurement as the primary guide.

How do I measure my chest for AMP merch?

Wrap a fabric tape under your armpits and across the fullest part of your chest. Keep it horizontal and snug but not tight. Write down the number to the nearest half-inch. This is your chest measurement.

Does AMP merch shrink after washing?

All AMP cotton items are pre-shrunk, but expect up to 3% shrinkage if you wash in hot water or dry on high heat. To minimize shrinkage, wash cold and tumble dry low or hang dry.

Are AMP sizes unisex?

Yes, both the Essential Tee and Premium Hoodie are cut unisex. They have a straight, relaxed silhouette. Women may prefer sizing down for a more fitted look.

AMP Merch Size Guide: Find Your Perfect Fit in 2026

Find your perfect AMP merch fit with our 2026 sizing guide. Measure yourself, compare to the official chart, and learn from real fan reviews to avoid size mishaps.

By Alex Rivera

Why AMP Merch Sizing Matters for Comfort and Style

You just got your hands on the new AMP drop - the hoodie you've been waiting for since the tour announcement. You unbox it, pull it over your head, and... the sleeves are two inches too long. The torso bunches up around your waist. It's not the oversized look you wanted - it's just wrong.

This is the exact frustration that makes an AMP merch size guide essential. With over 300,000 active fans in the community, sizing questions are the top reason people reach out to us. I've spent a decade studying print-on-demand fit, and the biggest challenge is that every garment cuts differently. A size L in the AMP Essential Tee fits like a relaxed medium, while the same size in the AMP Premium Hoodie runs true to size with a boxy cut. Without a guide, you're guessing.

This walkthrough covers everything: how to read the AMP size chart, how to measure yourself correctly, what real fans say about their fit experiences, and insider tips to get it right every time. By the end, you'll order with confidence and never return another piece.

AMP Size Chart: Hoodies, T-Shirts, and Accessories

Below is the official AMP size chart for our most popular items. All measurements are in inches and reflect the garment laid flat - not your body measurements. Remember: each product type has its own fit philosophy.

AMP Essential Tee (Unisex)

Size	Chest (in)	Length (in)	Sleeve (in)
XS	18	27	15.5
S	19	28	16
M	20	29	17
L	21.5	30	18
XL	23	31	19
2XL	25	32	20

This tee runs slightly relaxed. If you're between sizes, size down for a slim fit or up for a looser drape. The fabric is 4.3-ounce 100% combed ring-spun cotton - lightweight but structured, so it holds shape without clinging.

AMP Premium Hoodie (Unisex)

Size	Chest (in)	Length (in)	Sleeve (in)
XS	20	26	33.5
S	22	27	34.5
M	24	28	35.5
L	26	29	36.5
XL	28	30	37.5
2XL	30	31	38.5

This hoodie is roomier by design - expect an extra 2 inches in the chest compared to the tee. The 8-ounce 80/20 cotton-poly blend gives it a soft midweight feel. I recommend sticking with your normal size for a classic hoodie shape; sizing up adds that exaggerated streetwear length.

AMP Dad Hat (One Size)

Measurement	Inches
Circumference	20-23.5
Brim	3.25
Crown height	4.5

Unstructured cotton twill with an adjustable brass buckle back. It fits most head sizes from 6 5/8 to 7 3/8. If you have a larger head (above 23.5 inches), skip this one - the AMP Bucket Hat fits up to 24 inches.

How to Measure Yourself for the Best AMP Fit

Using a fabric measuring tape, follow these steps on bare skin or thin clothing. Write down numbers to the nearest half-inch.

Step 1: Chest - The Foundation

Wrap the tape under your armpits and across the fullest part of your chest - not just the ribcage. Keep it horizontal and snug but not tight. Breathe normally. My common mistake: people measure too high, resulting in a garment that pulls across the shoulders. For the AMP Essential Tee, a 40-inch chest maps to size L. If you're at 41 or 42, go to XL for comfort.

Step 2: Waist - For Sleeve Length (Hoodies Only)

Yes, waist matters for hoodie sleeves. Measure around your natural waist (belly button level). Then, measure from the center of your back, across your shoulder, and down to your wrist with arm slightly bent. Add your waist measurement to get the full sleeve length. For the AMP Premium Hoodie, a 34-inch sleeve length corresponds to size L. If your arm measurement is 35 inches, size up to XL.

Step 3: Length - The Final Check

Measure from the highest point of your shoulder (where a shirt seam sits) down to where you want the hem to fall. For the Essential Tee, I want the hem just below the belt line - that's 28 inches for a 5'9" person wearing size M. For the hoodie, hem at mid-hip is standard, about 30 inches for size L. Pro-tip: always round up to the nearest inch - a little extra length is more forgiving than too short.

Step 4: Compare to the Chart

Now match your numbers to the chart above. If your chest says L but your length says M, go with the larger size for the best overall fit. The chart is the authority - not your usual t-shirt size from other brands.

Real Fan Reviews: Fit Experiences with AMP Merch

The AMP community is active on Discord and Reddit, and I've compiled real feedback to help you decide. Here are three typical experiences:

Jenna (5'4", 140 lbs): “I bought the AMP Essential Tee in size M. It's slightly boxy but I love the relaxed look. Next time I might try S for a neater tuck. The sleeves hit just above my wrist - perfect for my height.”
Marcus (6'1", 200 lbs): “The hoodie in L fits well in the chest but the sleeves are a bit short. I wish I went with XL for the arm length. The cotton-poly blend is super soft though.”
Priya (5'8", 160 lbs): “The Essential Tee in L was too long for me - it covered my entire backside. I exchanged for M and it's perfect. I wish the size chart had a length measurement for each size.”

These reviews highlight a key point: the size chart is your starting line, not the finish. If you have a long torso or long arms, consider sizing up. If you're petite, sizing down might be better. And always factor in your preferred fit - relaxed vs. tailored.

Tips for Getting the Perfect AMP Merch Fit Every Time

Beyond the chart, here's what the AMP community has learned over countless drops.

Know Your Pre-Shrinkage

All AMP cotton items are pre-shrunk, but expect up to 3% shrinkage after the first wash if you use hot water or a high-heat dryer. To maintain fit, wash cold and tumble dry low. I lost a half-inch in length on my first hoodie before I learned this. Now I hang dry all my merch.

Use the Community as a Resource

Before ordering, search for photos of fans wearing the piece you want. People often post their stats and size in the AMP merch Discord. For example, searching "5'10" size L hoodie" will show you how it actually fits. This is more reliable than the chart alone.

Read Product Descriptions Carefully

Not all AMP shirts are the same. The Essential Tee is lightweight and relaxed; the Heavyweight Tee (when available) is a thicker 6-ounce fabric with a boxier cut. The same size can feel totally different. I always scan the fabric weight and fit notes before adding to cart.

When in Doubt, Go Up

Returning an item is a hassle. If you're between sizes on the chart, especially for hoodies, order the larger size. You can always wear it oversized or layer underneath. A too-small garment is unwearable; a slightly large one still looks intentional.

Check the Cuffs and Ribbing

Hoodie cuffs and hem bands can be tight, especially if you have larger hands or a broader hips. For the AMP Premium Hoodie, the ribbing is 2 inches wide with moderate stretch. If you struggle to get your hands through the cuffs, a size up will help without compromising the sleeve length.

Key Takeaways

Always measure yourself with a fabric tape and compare to the specific product chart - not your usual size.
T-shirts run slightly relaxed; hoodies are boxier with a true-to-size fit.
Real fan reviews show that height and arm length matter just as much as chest size.
Account for up to 3% shrinkage by washing cold and air drying.
When in doubt, size up - especially for hoodies.
