Buying underwear online in India often means decoding three different sizing systems at once. One brand uses S, M, L, another uses waist inches, and a third uses centimetres. This guide to the underwear size chart in India explains how those systems relate, shows Yazoo’s size chart, and helps you pick the right size without guessing.

Why Underwear Sizing Feels Confusing

There is no single national standard for men’s underwear sizing in India, so different brands label sizes in different ways:

• Letter sizes (S, M, L, XL, XXL): common on most modern brands and online stores.
• Waist in inches (for example 30, 32, 34): used by some brands and often resembles trouser-style sizing.
• Waist in centimetres (for example 80, 85, 90): used by some brands, which is why a “90” can look puzzling next to an “L”.

On top of that, the same letter can map to a different waist range depending on the brand. That’s why “I’m a medium” only works within one brand’s chart, and why it pays to check the chart for the brand you’re buying.

Yazoo Size Chart

Here is Yazoo’s size chart, based on your waist measurement:

Measure your natural waist, find the row that matches, and choose that size. If your measurement doesn’t land inside a range, read the next section.

What to Do If You’re Between Sizes

Yazoo’s ranges are written as steps with small gaps between them, so it’s common for a measurement to fall between two sizes. Yazoo’s guidance is to size down.

• Example from the chart: if your waist is between 85 cm and 90 cm, choose M rather than L.
• The same rule in inches: if your waist is between 30 and 32 inches, choose S rather than M.

Sizing down works because the fabric has stretch and is designed to fit close to the body. If you want to understand why stretch matters, our guide to 4-way stretch fabric explains it. Since innerwear is typically final sale for hygiene reasons, it’s worth double-checking your measurement before you order.

Waist Inches to cm Conversion Chart

If a brand lists sizes in a different unit from the one you measured in, the conversion is exact: 1 inch equals 2.54 cm. Here are common waist measurements, rounded to the nearest centimetre.

To convert your own number, multiply inches by 2.54 to get centimetres, or divide centimetres by 2.54 to get inches.

How to Measure Your Waist

For underwear, measure your natural waistline, which sits just above your hip bones where a waistband naturally rests:

1. Use a soft measuring tape.
2. Stand relaxed and keep the tape snug but not tight.
3. Note the number in inches or cm, then match it to the chart.
4. Compare it to the brand’s chart rather than your usual size.

Our step-by-step men’s underwear size guide walks through this in more detail, including common mistakes. If you’re also deciding on a style, our briefs vs trunks guide explains how the two fit differently.

Common Sizing Mistakes

• Assuming your size is the same across brands. Letter sizes and waist ranges vary, so use each brand’s own chart.
• Mixing up inches and centimetres. A number like 90 on one brand is a waist in cm, not inches.
• Using trouser size as a guide without checking. Underwear is often sized differently from trousers, so a rough match isn’t enough.
• Sizing up “just in case.” For Yazoo, the guidance for in-between measurements is to size down.
• Not re-measuring. Your waist can change over time, so an old size may no longer fit.

FAQs

How do I convert waist inches to cm?
Multiply the measurement in inches by 2.54. For example, 32 inches is about 81 cm.

Is there a standard underwear size chart in India?
No. Sizing varies by brand, so always check the chart for the specific brand you’re buying.

What are Yazoo’s waist sizes for medium and large?
Yazoo’s M fits a waist of 80-85 cm (32-34 inches) and its L fits 90-95 cm (36-38 inches).

What size should I choose if I’m between two sizes?
Yazoo suggests sizing down. For example, if your waist is between 85 cm and 90 cm, choose M rather than L.

Why do some Indian brands list sizes like 85 or 90?
Those are typically waist measurements in centimetres, so you compare them to your waist in cm rather than treating them as letter sizes.

Which sizes does Yazoo’s size chart cover?
The chart covers S, M, L, XL and XXL, with waist ranges from 70 cm (28 inches) up to 115 cm (46 inches).

Final Word

The underwear size chart in India isn’t one universal chart but a set of brand-specific ones. Measure your waist, match it to the brand’s chart, and follow its guidance for in-between sizes. When you’re ready, browse Yazoo’s shop and use the chart above to choose your size.
