Atmora Size Guide

Find the fit that feels right.

Use this guide to compare Atmora garment measurements with a shirt you already own and like. The chart below uses shirt measurements — not body measurements — so the easiest method is to measure a well-fitting shirt laid flat.

01 / IMPORTANT

Garment Measurements

The numbers in this guide describe the shirt itself, not your body measurement.

02 / BEST METHOD

Compare a Shirt

Measure a shirt you already like and compare those measurements with the Atmora chart.

03 / BETWEEN SIZES

Prefer More Room?

If you fall between two sizes, consider the larger size when you want an easier fit.

04 / PRODUCT PAGE

Specific Notes Win

If a product page shows its own size or fit guidance, use that product-specific information first.

01 — Size Chart

Atmora shirt measurements.

All measurements are in inches and refer to the garment. Minor production variation may occur. For the best comparison, use a similar shirt laid flat.

Size Chest Shoulder Length Full Sleeve Half Sleeve
S 38" 16" 27.5" 24.5" 7.5"
M 40" 17" 28" 25" 8"
L 42" 18" 29" 25" 8"
XL 44" 19" 30" 25.5" 8.5"
XXL 46" 20" 31" 25.5" 9"
All values are in inches. Use a measuring tape and keep it straight, relaxed, and aligned with the garment.
These are garment measurements. Do not compare these values directly with your body chest measurement without allowing for fit/ease.
Product-specific guidance has priority. If a product page shows different fit or measurement information, follow that product page.

02 — How to Measure

Measure a shirt you already trust.

The easiest way to choose an Atmora size is to compare the chart with a shirt that already fits the way you like. Button it, lay it flat on a smooth surface, and measure without pulling or stretching the fabric.

01

Chest

Measure across the shirt around the chest area while it is laid flat. Use the garment measurement convention shown in the chart.

02

Shoulder

Measure straight across the back from one shoulder seam to the other.

03

Length

Measure from the highest shoulder point down to the bottom hem of the shirt.

04

Sleeve

For a full sleeve, measure from the shoulder seam to the cuff. For a half sleeve, measure from shoulder seam to sleeve end.

03 — Fit Guidance

Choose based on how you like your shirts to feel.

Two people with similar body measurements may still prefer different sizes. Your ideal choice depends on shoulder comfort, chest room, styling preference, and how you plan to wear the shirt.

Prefer a Cleaner Fit

Choose the size that most closely matches the measurements of a shirt you already wear with a neat, closer silhouette.

Prefer More Ease

If you like extra movement through the chest or midsection, compare with a roomier shirt and consider the larger size.

Between Two Sizes

If your comparison falls between sizes, sizing up is usually the safer direction when comfort and extra room matter more.

Check the Product Page

Some fabrics, patterns, cuts, or product constructions may have their own specific size note. Follow that information first.

04 — Best Sizing Method

Three steps before you place the order.

This simple comparison method is more reliable than choosing a size only from habit, especially when different brands use different sizing conventions.

01

Pick your best-fitting shirt.

Choose a shirt with a similar style and fit to what you expect from Atmora. Avoid comparing with oversized, stretch-heavy, or unusually slim pieces unless that is the fit you actually want.

02

Measure it on a flat surface.

Button the shirt, smooth it naturally, and measure chest, shoulder, length, and sleeve without pulling the fabric.

03

Match the closest Atmora size.

Compare your measurements with the chart. If two sizes are close, use your preferred fit and the product-specific note to decide.

05 — Important Size Notes

Two details worth checking every time.

The general size chart is a strong starting point, but a product’s own fit information and your personal fit preference should always be part of the final decision.

Product-specific sizing overrides the general chart.

If an Atmora product page includes a different size note, fit note, or measurement table, use that information for that product because fabric and construction can affect how a shirt wears.

Do not choose only from your usual letter size.

A “M” or “L” can differ from one brand to another. Comparing actual garment measurements is more useful than assuming your usual size will always match exactly.
