Avoid the most common sizing mistake by learning how to read size charts, compare measurements, and pick the right fit for every category.
Why Sizing Is the Most Common Mistake
Sizing errors are the number one reason for returns and exchanges on RizzitGO. The problem is not the platform. The problem is assumptions. Buyers assume their usual size will match. They assume Medium is the same across all brands. They assume the size chart is a suggestion rather than a measurement. These assumptions lead to disappointment. This guide teaches you how to choose size correctly, every time, in every category.
The first principle is that size charts are measurements, not suggestions. A Medium on one factory may have a fifty-two centimeter chest. A Medium on another may have a fifty-six centimeter chest. That four centimeter difference is the difference between a good fit and a bad fit. The only way to know is to measure a garment you already own and compare it to the chart. This takes two minutes and prevents ninety percent of sizing issues.
How to Measure Yourself Correctly
Chest
Measure around the widest part of your chest, keeping the tape level. Do not pull tight.
Shoulders
Measure from the tip of one shoulder to the other across your back.
Sleeve
Measure from the shoulder seam to the wrist bone.
Waist
Measure around your natural waistline, not your hips.
Inseam
Measure from the crotch to the ankle bone along the inside of your leg.
Foot Length
Place your foot on a piece of paper, mark the heel and toe, and measure the distance.
Category-Specific Sizing Tips
Asian vs Western Sizing
Most items on RizzitGO are produced in Asian factories. Asian sizing runs smaller than Western sizing. A Large in Asian sizing may be equivalent to a Medium in Western sizing. This is the most common source of confusion. The size chart is your only reliable guide. Never assume the label size. Always convert using the centimeter measurements. If the chart is missing, ask your agent for the measurements before ordering. Do not guess.
If the size chart only lists one measurement, like chest width, ask for the full chart. A single measurement is not enough to judge fit. You need at least chest, length, and shoulder for tops, and waist and inseam for bottoms.
What to Do When You Are Between Sizes
If your measurement falls between two sizes, the rule depends on the item. For tops, if you want a relaxed fit, size up. If you want a fitted look, size down. For bottoms, size up is usually safer. Tight pants are uncomfortable. Loose pants can be adjusted with a belt. For shoes, size up is safer if you are between sizes. Shoes that are too tight cause blisters. Shoes that are slightly loose can be fixed with insoles or thicker socks.
Using QC Photos for Sizing Confirmation
Before shipping, you can request your agent to measure the actual item and include the numbers in the QC photos. This is the most accurate way to confirm sizing. The agent lays the item flat, measures it with a tape, and photographs the measurement. This removes all guesswork. If the measurement does not match the chart, you can exchange immediately. This service is usually free or low-cost. It is worth using for every order, especially your first few.
