Men's Shirt Fitting Guide: Get the Right Size Every Time
Shoulder width, chest, sleeve length — the measurements that matter when buying readymade shirts. A practical guide from Sheetal Readymade, Biswan.
The number one reason men look bad in readymade shirts isn’t the fabric or the brand — it’s the fit. A ₹799 shirt that fits perfectly will always look better than a ₹2,500 shirt that doesn’t.
The problem? Most men buy shirts by just one measurement: “M/L/XL.” That’s like buying shoes by saying “medium.” It doesn’t work.
Here’s how to actually get the right fit.
The 5 Measurements That Matter
1. Shoulder Width
This is the single most important measurement. Get this wrong and no amount of tailoring fixes it.
How to measure: From the edge of one shoulder bone to the other, across the back. The seam of the shirt should sit exactly at the shoulder point — not drooping down your arm, not riding up on your neck.
Signs it’s wrong:
- Seam falls below the shoulder → shirt is too big
- Seam sits on top of the shoulder near the neck → shirt is too small
- Fabric bunches at the upper back → too wide
2. Chest
How to measure: Wrap a tape measure around the fullest part of your chest, under your arms. Keep it level. Don’t puff out or suck in.
The rule: Your shirt chest measurement should be 3-4 inches more than your body chest measurement. This gives you room to move, breathe, and sit without buttons straining.
Signs it’s wrong:
- Buttons pull or gap when you stand straight → too tight
- Fabric balloons out at the sides → too loose
- You can’t comfortably cross your arms → too tight
3. Sleeve Length
How to measure: From the shoulder point down to the wrist bone. Your arm should be slightly bent (not straight, not fully bent).
The rule: The shirt cuff should end at the wrist bone. When wearing a blazer, about 1 cm of shirt cuff should show.
Signs it’s wrong:
- Cuff covers your hand → too long
- Cuff sits above the wrist → too short
- You keep pushing sleeves up because they annoy you → too long
4. Body Length
How to measure: From the base of the neck (where the collar sits) straight down to mid-hip.
The rule: A formal shirt should be long enough to stay tucked in when you raise your arms. A casual shirt should end at mid-hip — covering the belt but not looking like a kurta.
Common mistake: Buying shirts that are too long and then bunching all that extra fabric into your trousers. It creates bulk around the waist and looks sloppy.
5. Collar
How to measure: Around the base of your neck where the collar sits. Add half an inch for comfort.
The rule: You should be able to fit two fingers between your neck and a buttoned collar. One finger = too tight. Three fingers = too loose.
Why it matters: A collar that’s too tight is genuinely uncomfortable and shows in your face (you’ll look strained). Too loose and the collar doesn’t sit properly.
Your Size Chart Reference
Here’s a general ready-to-wear size chart. Individual brands vary, so always try before buying.
| Size | Chest (inches) | Shoulder | Sleeve | Collar |
|---|---|---|---|---|
| S | 36-38 | 16-16.5 | 24 | 15 |
| M | 38-40 | 17-17.5 | 24.5 | 15.5 |
| L | 40-42 | 18-18.5 | 25 | 16 |
| XL | 42-44 | 19-19.5 | 25.5 | 16.5 |
| XXL | 44-46 | 20-20.5 | 26 | 17 |
Important: These are body measurements, not shirt measurements. The shirt will have ease added.
How to Measure Yourself at Home
You’ll need a soft measuring tape (the kind used for sewing, not a metal one).
Step 1: Wear a well-fitted t-shirt or vest. Don’t measure over a thick kurta or jacket.
Step 2: Stand straight with arms relaxed at your sides. Don’t flex, don’t slouch.
Step 3: Have someone else take the measurements. Measuring yourself leads to inaccurate numbers, especially for shoulders and back.
Step 4: Measure twice. Write it down. Bring it to the shop.
Fit Types Explained
Slim Fit
- Close to the body with minimal excess fabric
- Looks sharp and modern
- Best for lean to average builds
- Not the same as tight — you should still be able to breathe and move
Regular Fit
- Standard ease through the chest and waist
- Comfortable for all-day wear
- Works for most body types
- Our most popular fit at the shop
Relaxed Fit
- Extra room through chest, waist, and arms
- Maximum comfort
- Better for larger builds or anyone who prioritises comfort over silhouette
- Tuck in to avoid looking shapeless
Common Fitting Mistakes
1. “I’ll grow into it” No. Buy clothes that fit you now. A shirt that’s too big looks worse than one that’s slightly small.
2. Ignoring the back A shirt might look fine from the front but have massive excess fabric at the back. Always check the mirror from behind.
3. Only checking with arms down Move around in the trial room. Raise your arms, cross them, sit down. A shirt needs to work in motion, not just standing still.
4. Confusing comfort with fit A shirt that feels like a tent isn’t “comfortable” — it’s oversized. A well-fitted shirt should feel snug but not restrictive.
When to Get Alterations
Some things can be altered on readymade shirts, some can’t:
| Alteration | Possible? | Cost |
|---|---|---|
| Sleeve length (shorten) | Yes | ₹50-100 |
| Body length (shorten) | Yes | ₹80-150 |
| Side seams (take in) | Yes, up to 2 inches | ₹100-200 |
| Shoulder width | No (too structural) | — |
| Collar size | No | — |
The takeaway: Get the shoulders and collar right at the store. Everything else can be adjusted.
