SuperBuy Sizing Guide: How to Get the Right Fit Every Time

Why Sizing Is the #1 Problem on SuperBuy

Sizing issues are the most common reason for returns and exchanges on SuperBuy. The problem is not that the products are poorly made; it is that the size charts are based on Asian sizing standards, which differ from US and EU standards. If you order your usual size without checking the chart, you will likely receive an item that is too small.

This guide explains how to measure yourself, how to read SuperBuy size charts, and how to convert between sizing systems. Following these steps will save you from the most frustrating mistake in the buying process.

How to Measure Yourself

Before you can match a size chart, you need accurate measurements. Here is what to measure for clothing and shoes:

For Clothing:

• **Chest/Bust**: Measure around the fullest part of your chest, keeping the tape level
• **Waist**: Measure around your natural waistline, typically the narrowest part
• **Hips**: Measure around the widest part of your hips
• **Shoulder width**: Measure from shoulder tip to shoulder tip across your back
• **Sleeve length**: Measure from shoulder tip to wrist
• **Inseam**: Measure from crotch to ankle along the inner leg

For Shoes:

• **Foot length**: Place your foot on a piece of paper, mark the heel and longest toe, and measure the distance in centimeters
• **Foot width**: Measure the widest part of your foot
• **Arch length**: Measure from heel to the ball of your foot

**Pro tip:** Measure yourself while wearing the type of undergarments you would wear with the item. For shoes, measure at the end of the day when your feet are slightly swollen.

How to Read SuperBuy Size Charts

Size charts on SuperBuy typically list measurements in centimeters. Each size (S, M, L, XL, etc.) corresponds to a range of measurements. Here is how to interpret them:

1. **Find your key measurement**: For shirts, the chest measurement is usually the most important. For pants, the waist and inseam matter most. For shoes, the foot length is critical.

2. **Compare to the chart**: Look at the size chart for the specific item and find the size where your measurement falls within the range.

3. **Add a buffer**: If you are between sizes, consider the fit you want. For a loose fit, size up. For a tight fit, size down. A general rule is to add 2-3 cm to your chest measurement for a comfortable fit in shirts.

4. **Check the garment measurement, not the body measurement**: Some charts list the actual garment dimensions (which are larger than body measurements). Others list the recommended body measurements. Make sure you know which one the chart is showing.

Asian Sizing vs. US Sizing

Asian sizing runs approximately one size smaller than US sizing. Here is a rough conversion table:

This is a general guideline. Always check the specific size chart for the item you are ordering, as different sellers may use different sizing standards.

Shoe Sizing on SuperBuy

Shoe sizing is the most complex category because different brands use different lasts (foot molds). The safest approach is to measure your foot length in centimeters and match it to the size chart.

Common conversion for men's shoes:

**Important:** QC photos often include a measurement of the insole. If the insole measurement in the QC photo does not match your foot length, the shoe will not fit. This is the most reliable sizing check for shoes.

What to Do When the Size Chart Is Missing

Some listings on SuperBuy do not include a detailed size chart. In these cases:

1. **Check the item description**: Sometimes the measurements are listed in the text instead of a chart.

2. **Ask the seller**: Use the SuperBuy messaging feature to request measurements before ordering.

3. **Check Reddit**: Search r/SuperBuy for the item or seller to see if other buyers have posted sizing information.

4. **Order with caution**: If you cannot find sizing information, consider ordering a size up as a safer bet, or choose a different listing.

Sizing for Specific Categories

**Shoes:** Always use foot length in centimeters. Never guess based on your usual size. Check the QC insole measurement.

**Shirts and Hoodies:** The chest measurement is the most important. Add 2-4 cm for a comfortable fit, more for an oversized look.

**Pants:** Waist and inseam are both critical. If you are between sizes, prioritize waist fit over inseam (inseam can be adjusted by a tailor).

**Jackets:** Measure your chest with a shirt on, then add 4-6 cm for layering room. Shoulder width is also important for a proper fit.

**Headwear:** Measure your head circumference. Caps usually have adjustable straps, but beanies and fitted hats need accurate sizing.

When to Size Up

Consider sizing up in these situations:

• The item is described as "slim fit" or "fitted"
• You are between sizes on the chart
• You prefer a loose or oversized fit
• The item is a jacket or hoodie that you plan to layer over other clothing
• The material is known to shrink (check fabric composition)

When to Size Down

Consider sizing down in these situations:

• The item is described as "oversized" or "relaxed fit"
• The material is stretchy (spandex, elastane blends)
• You prefer a tight fit
• The item is a t-shirt or tank top where you want a close fit
