Step-by-Step Guide
Step 1: Find Your Base Size with the Official Size Chart
Start with the size chart on each product page. Articles of Interest uses standard US sizing for unisex garments. For tees, a size Medium typically fits a 38-40 inch chest. Hoodies in Medium accommodate a 38-40 inch chest as well, but note the length is about 28 inches from shoulder to hem. Write down the measurements for your usual size across different product types.
Pro tip: Don't go by your usual shirt size alone. Many fans report that the heavyweight articles of interest merch store tee (the one with the boxy cut) fits a half size larger than the classic tee. Check the specific product chart.
Step 2: Measure Your Chest, Shoulders, and Torso Length
Use a soft measuring tape. For chest: wrap around the fullest part of your chest, under your armpits. Keep the tape snug but not tight. For shoulders: measure from the edge of one shoulder to the other across your back. For torso length: measure from the highest point of your shoulder down to where you want the hem to fall. Standard hoodies hit at the hip (about 27-28 inches from shoulder).
Pro tip: Measure your favorite well-fitting apparel collection or articles of interest merch store hoodie flat on the floor. Compare those numbers to the size chart. This is more accurate than measuring your body because you account for how you like the garment to drape.
Step 3: Account for Shrinkage in Preshrunk Fabrics
Articles of Interest uses preshrunk cotton in most tees and hoodies. Still, with the heavyweight fabrics (like the 10 oz fleece hoodies), you might see about 2-3% shrinkage in length after the first wash. If you're between sizes and prefer a longer fit, size up. For the tri-blend tees (which include polyester), shrinkage is minimal - less than 1%.
Pro tip: Wash all your fan merch in cold water and tumble dry on low to minimize any size changes. I've had a Medium heavyweight tee stay perfectly fitted after a year of careful washing.
Step 4: Decide on Oversized vs Fitted
Do you want a relaxed streetwear look or a more tailored fit? For oversized, add 2-4 inches to your chest measurement compared to the chart for your typical size. For example, if you usually wear a Medium (38-40 chest), order a Large (42-44) for a relaxed hip-hop inspired silhouette. For a fitted look, stick to your chest measurement. The classic tee and hoodie are designed to be slightly relaxed, not tight.
Pro tip: If you're between sizes and can't decide, the community overwhelmingly prefers sizing up for hoodies. The extra room makes layering easy and keeps the fit comfortable.
Step 5: Check the Product-Specific Notes
Every product page includes a note about fit. Some shirts have a "standard fit" tag, others are labeled "athletic fit" (narrower through the body). The hoodies are all standard fit unless marked. The fleece joggers run true to size but are snug in the thigh - if you have larger legs, size up once.
Pro tip: Read reviews! Fans often post their measurements and what they ordered. I've seen hundreds of comments like "5'10, 160 lbs, Medium classic tee fits great." Use these as benchmarks.
