How Should a Pea Coat Fit? A Men's Sizing and Styling Guide
Short answer: a pea coat should sit clean at the shoulders, button over a shirt or sweater without pulling across the chest, end its sleeves around your wrist bone, and cover your belt and hips. Fit matters more on a pea coat than on most jackets, because it's a structured coat that doesn't stretch. Choose your size from the garment measurements, not from the letter you usually buy.
What is a pea coat?
The original pea coat was a short, heavy, double-breasted naval coat with broad lapels. Today the name covers a family of tailored, hip-to-thigh-length coats, including single-breasted versions with a turn-down collar. It sits between a casual jacket and a formal overcoat: smart enough for the office, easy enough for weekends.
How should a pea coat fit?
- Shoulders: the shoulder seam should sit at the edge of your shoulder. No overhang, and no dents in the sleeve below it.
- Chest: button it over the layer you'll actually wear. The fabric shouldn't pull into an X shape around the buttons.
- Sleeves: with your arms down, the sleeve should end around your wrist bone and cover most of your shirt cuff.
- Length: it should cover your belt and hips.
- Reach test: stretch your arms forward as if you're driving. It can feel snug across the back, but it shouldn't strain at the seams.

How do you size a pea coat that runs small?
Our Men's Single-Breasted Long Pea Coat has a slim, tailored cut in a non-stretch fabric, and it runs small. Measure your body chest around the fullest point, just under your arms, over a thin shirt. Then pick a size whose garment chest is at least 4 to 6 inches larger. If you'll wear it over a thick sweater, or you land between sizes, go one size up.
| Size | Garment chest (in) | Body chest it fits (in, approx.) | Coat length (in) |
|---|---|---|---|
| M | 39.4 | 33 to 35 | 27.2 |
| L | 40.9 | 35 to 37 | 28.0 |
| XL | 42.5 | 36.5 to 38.5 | 28.7 |
| 2XL | 44.1 | 38 to 40 | 29.5 |
| 3XL | 45.7 | 39.5 to 41.5 | 30.7 |
| 4XL | 47.2 | 41 to 43 | 31.5 |
| 5XL | 49.6 | 43.5 to 45.5 | 32.7 |
Because of how small this cut runs, many men end up two or three sizes above the letter they usually buy. That's expected. Go by the numbers.
Classic or fleece-lined?
The coat comes in two styles with the same cut, colors and size chart. The classic style is mediumweight, right for fall and milder winter days. The fleece-lined style adds a soft lining for colder days. If you commute on foot or wait for trains in winter, pick the fleece-lined one.
What do you wear with a pea coat?
- For the office: a dress shirt or a fine-knit sweater, trousers or chinos, and leather shoes or boots.
- For weekends: a crewneck sweater, dark jeans and boots.
- For colder days: add a scarf and a beanie, and a thicker sweater if you sized for it.
Dark blue is the classic pea coat color and goes with almost everything. Black is the sharpest for the office. Light khaki, dark khaki and military green look more relaxed with jeans. For warm layers to wear underneath, see the best warm sweatshirts and sweaters for layering.
Frequently asked questions
Should a pea coat be tight?
It should be trim, not tight. You should be able to button it over a shirt or light sweater and reach forward without the buttons pulling.
Can you wear a hoodie under a pea coat?
You can for a casual look, but only if you sized up for it. A hood adds bulk at the collar, so a crewneck sweater sits more cleanly.
Is a pea coat warm enough for winter?
For city winters with a sweater underneath, yes, especially a fleece-lined one. For snow, deep cold or long hours outside, a hooded parka or an insulated work jacket is the better choice.
What's the difference between single-breasted and double-breasted?
A double-breasted coat has two columns of buttons and overlapping front panels, the traditional naval style. A single-breasted coat has one column of buttons, which looks cleaner and works more easily with casual clothes.
How do you care for a pea coat?
Follow the care label. For our pea coat, gentle hand washing in cold water or professional cleaning is recommended. Don't bleach, and air dry it flat or on a hanger so it keeps its shape.
