GTBuy Size Guide: How to Measure and Choose the Right Fit

Sizing is the most common source of disappointment when buying reps. A medium in one batch might fit like a large in another. This guide teaches you how to measure yourself, read size charts, and choose the right fit across every GTBuy category.

How to Measure Yourself

Use a soft tape measure. For clothing, measure your chest, waist, hips, shoulder width, and arm length. For shoes, measure your foot length in centimeters. For pants, measure your inseam, thigh width, and rise. Write these numbers down and keep them accessible.

Reading Size Charts

Size charts are not universal. A medium from one factory is different from a medium at another. Always compare the chart to your measurements, not to your usual size. If the chart says the medium chest is 40 inches and your chest is 42 inches, order a large. Do not assume the medium will fit because you usually wear medium.

Shoes Sizing

Shoe sizing is the most complex. US, UK, EU, and CM sizes all convert slightly differently. Always measure your foot in centimeters and compare to the factory chart. Do not convert from US to EU without checking. Different factories produce different fits. If you are between sizes, go up half a size for sneakers and down half a size for boots.

Hoodies and Sweaters Sizing

Hoodies have the most variation in fit. Oversized fits add 2-4 inches to the chest and length. Check the measurement table for every item. If you want a standard fit, order true to size. If you want the oversized look, do not size up. The item is already oversized.

T-Shirts Sizing

T-shirt sizing is straightforward but inconsistent. Always check the length and chest measurements. If you want a cropped look, check if the item is already cropped or if you need to size down. For a boxy fit, look for items with a wide chest and short length.

Jackets Sizing

Jackets require room for layering. Measure your chest while wearing a hoodie or sweater, then add 1-2 inches for movement. If you want a tight puffer look, size down but verify the fill power will still keep you warm.

Pants and Shorts Sizing

Measure your best-fitting pair of pants and compare every dimension. Do not rely on waist size alone. The inseam, thigh width, and rise are the real determinants of fit. For shorts, check the outseam to know where they will fall on your leg.

Headwear Sizing

For fitted caps, measure your head circumference and compare to the size chart. For snapbacks, most fit standard sizes. Beanies are usually one-size, but check the stretch percentage if you have a larger head.

Jerseys Sizing

Jerseys are designed to fit over athletic wear. If you want a tight fit, size down. If you want to wear it over a hoodie, size up. Check the length and sleeve measurements specifically.

Accessories Sizing

Belts should be sized by measuring your waist over the pants you will wear. Bags should be checked by dimensions, not just photos. Jewelry usually has adjustable sizing, but chains have fixed lengths.

Final Tips

Always keep your measurements written down. Update them every six months. Check the size chart for every item, even if you have ordered from the same seller before. If you are between sizes, go up for comfort and down for a tight fit. When in doubt, ask the community.
