How to Measure for a Blazer

Finding the correct blazer size is crucial for a comfortable fit that complements your shape and allows freedom of movement. Wearing a properly fitted blazer helps avoid issues like pulling, bunching, or sagging, enabling you to look and feel your best throughout the day. By following a few key steps and using simple tools, you can take accurate measurements for yourself at home or provide them when shopping online or with a tailor.

Key Measurement Points

Chest

Stand upright with relaxed shoulders and arms at your sides. Position a soft, non-stretch tape measure around the fullest part of your chest, ensuring the tape is just under your arms and across your shoulder blades. The tape should feel snug but not restrictive, and must remain parallel to the ground for accuracy.

Shoulder Width (Point to Point)

Measure from the end of one shoulder seam (where the sleeve meets the jacket body) straight across the top of your back to the end of the opposite shoulder seam. This point-to-point measurement helps guarantee the blazer sits correctly on your shoulders without feeling tight or slipping off.

Jacket Length

Start at the highest point of your shoulder, close to where the neck meets the shoulder. Measure straight down to your preferred hemline; traditionally, this is at the midpoint of the palm with your arms relaxed, but it can vary with style and preference.

Sleeve Length

Keep your arm slightly bent. Measure from the shoulder seam down the outside of your arm to about one inch past your wrist bone. This leaves space for a bit of your shirt cuff to show, which is customary.

Waist

Wrap the measuring tape around your natural waist, keeping it parallel to the ground. This is especially important for fitted blazers, ensuring the blazer closes comfortably without excess tightness or pulling.

Hips (Applicable for Certain Styles)

For blazers with a more tailored shape—often women's styles—measure around the fullest part of your hips, above the tops of your legs.

First Button Position and Bottom Hem

For a precise fit, you may want to note the distance from the top of your shoulder to the position of the blazer’s first button, as well as the width straight across the bottom hem.

Tools and Measurement Techniques

Use a flexible, soft tape measure for best results. Take measurements over thin, fitted clothing or directly on the skin for the greatest accuracy. Hold the tape snugly without pulling it excessively tight or leaving it loose. For circumference measurements (chest, waist, hips), ensure that the tape is straight and parallel to the floor. If you prefer a looser fit, consider adding an extra centimeter or so to your measurements. If you already own a blazer that fits well, lay it flat and take measurements from the garment at the key points listed above. For shoulder, back, or other hard-to-reach areas, use a mirror or ask someone to assist.

Common Mistakes When Measuring for a Blazer

Measuring over bulky clothing, like sweaters, can result in overly generous measurements and a loose fit. Pulling the tape too tight or allowing it to sag can distort the result. Failing to keep the tape parallel to the ground produces inaccurate numbers, especially on chest, waist, and hips. Slouching or standing in an unnatural posture can affect measurements. Omitting important points like shoulder width or not recording preferred jacket length may make it harder to find the right size.

Gender-Specific Measurement Considerations

Men’s blazers typically correspond directly to chest measurement in inches, with the main focus on chest, shoulder, and length. Women’s sizing may correspond to dress size or require bust, waist, and hip measurements for a more contoured fit. The importance of hip measurement, tailored waist, and more shaped silhouette is greater in women’s blazers than in men’s, which often follow a straighter pattern. The placement of buttons and overall jacket curvature may also influence where and how you take your measurements.

Sizing Differences Across Brands

Sizing systems can vary: some brands size by chest measurement in inches or centimeters, while others use S, M, L, or numerical dress sizing. Length notations such as “Short,” “Regular,” and “Long” are commonly used, especially in men’s blazers, to denote torso and sleeve length. Always consult the specific brand’s size guide, comparing your measurements directly to their recommendations for a proper fit.

Should You Measure Over Thick Clothing?

Avoid measuring over thick or heavy garments like sweaters, as this leads to inaccurate and larger measurements. For accuracy, measure over a light, fitted shirt or over bare skin. If you intend to wear your blazer over thicker layers, adding an extra centimeter to each measurement may provide the desired comfort.
