To measure your shirt size at home, wrap a soft tape around the fullest part of your chest, just under the armpits, and match that number to the brand's chart. Then check neck, shoulder and sleeve, because chest decides the size and the other three decide whether it fits.
Key takeaways
- Chest is the one measurement that picks your size. Measure it over a thin vest, with arms down.
- Shoulder seams should sit on the edge of your shoulder bone. Off by 2 cm or more and the shirt looks borrowed.
- Slim fit shirts need roughly 5 to 10 cm of room over your body chest. Regular fit needs more.
- Measure a shirt you already like, laid flat. It is the fastest check against any size chart.
- Derby shirts run S to 2XL or S to 3XL depending on the style, so check the size list before you pick a design.
What do you need to measure your shirt size?
You need a soft tailor's tape, a mirror and ideally one other person. A steel tape or a charger cable bends wrong and adds 2 to 3 cm of error.
Wear a thin vest or nothing on top.
How do you measure your chest for a shirt?
Place the tape under your armpits, across the fullest part of your chest and around the shoulder blades. Keep it level, breathe out normally and read the number without pulling tight.
Two fingers should slide under the tape. If you hold your breath or puff up, you will order a size that feels tight by lunch.
How do you measure your neck, shoulder and sleeve?
Neck
Wrap the tape around the base of your neck, where a collar sits, with one finger inside.
Shoulder
Measure across your back from the tip of one shoulder bone to the other. The shirt's shoulder seam should land right there.
Sleeve
Start at the shoulder tip, bend your arm slightly and run the tape down to the wrist bone. A full sleeve should end at the base of your thumb when your arm hangs straight.
Why measure a shirt you already own?
A shirt you like is proof of what fits your body. Lay it flat, button it, and measure straight across from armpit to armpit, then double that number.
Compare that doubled figure to the chest number on the size chart.
How much room should a slim fit shirt have?
A slim fit shirt usually needs about 5 to 10 cm more than your body chest, and a regular fit needs about 10 to 15 cm. Less than 5 cm and the buttons pull into an X shape across your chest.
In Chennai heat, a little extra room helps air move between the fabric and your skin. If you sit between two sizes in slim fit and spend the day outdoors, go up.

Frequently asked questions
Should I measure my chest or my stomach for a shirt?
Measure both and use the bigger number. If your stomach measures more than your chest, buttons will pull at the middle in your chest size.
Is shirt size the same as T-shirt size?
Often it is close, but most woven shirts have little stretch. A T-shirt in M can feel fine while a slim shirt in M feels tight.
What size is the Derby model wearing?
The product pages note the model wears size M and is 6 feet tall.
Do Derby shirts come in 3XL?
Many do. In the table above, the brown checks regular fit and teal stripes slim fit list 3XL. Others stop at 2XL.
Should I size up if I am between sizes?
Size up for regular fit and for long outdoor days in the heat. Stay with the smaller size in slim fit only if the shoulders already sit right.
