How to Measure for a Corset: A Step-by-Step Sizing Guide

Quick Answer

To measure for a corset, use a soft tape measure to record your natural waist, underbust, and high hip—each in inches. Then subtract 4 to 6 inches from your waist for a typical training corset, and use the underbust and hip measurements to confirm the corset will close without gaping. Always measure while standing, breathing normally, and wearing minimal clothing.

Getting the right corset size is the difference between a comfortable, flattering fit and a frustrating squeeze. Unlike standard clothing, corsets are designed to reduce your waist, so you can’t just order your dress size. The good news? With a tape measure and about 10 minutes, you can confidently find your corset size at home.

This guide walks you through the three key measurements—natural waist, underbust, and high hip—explains how to read a corset size chart, and shares practical fitting tips to help you avoid common sizing mistakes. Whether you’re new to waist training or adding another piece to your collection, these steps apply to most steel boned corsets.

What You Need Before You Start

Gather a soft, flexible tape measure—the kind used for sewing—and stand in front of a mirror. Wear thin, form-fitting clothing or none at all; bulky layers will add inches and throw off your numbers. If you don’t have a fabric tape, a piece of string and a ruler work, though a tape measure is easier.

Take all measurements while standing, feet hip-width apart, and breathing normally. Don’t suck in your stomach or hold your breath. Consistency matters more than perfect numbers—so measure the same way each time, and you’ll get a reliable baseline for your corset size.

• Use a flexible tape measure; a rigid ruler won’t follow your body’s curves.
• Measure at the same time of day—your waist can vary by an inch or more from morning to evening.

Step 1: Measure Your Natural Waist

Your natural waist is the narrowest part of your torso, usually about an inch above your belly button. Bend to the side to find the crease, then wrap the tape measure around that point. Keep it parallel to the floor and snug, but not so tight that it digs in. Take a breath and relax—this is your natural waist measurement, not the laced-down number.

For most waist training corsets, you’ll want a corset that is 4 to 6 inches smaller than this measurement. If you’re new to tightlacing, start with a 4-inch reduction; experienced wearers may aim for more. But remember, the underbust and hip measurements are just as important—they determine whether the corset actually fits your torso.

As you measure, keep these tips in mind:

Wrap the tape at the exact narrowest point—too high or too low will give a wrong size.

Don’t pull the tape tight; it should lie flat against your skin without compressing.

Write down the number before you move on—it’s easy to forget.

Step 2: Measure Your Underbust

The underbust is the circumference of your ribcage, directly under your bust. Wrap the tape measure around your torso at that level, making sure it sits horizontally and feels snug but not restrictive. This measurement is critical because a corset’s top edge needs to close comfortably around your ribs—if the underbust is too small, the corset won’t close; if it’s too large, it will gap.

When you later check a corset’s size chart, compare your underbust to the corset’s underbust measurement (often listed as the top edge circumference). Many corsets, like the Plus Size Artemis Hourglass Silhouette Corset in Black Mesh, are designed to accommodate a range of underbust sizes, so you may still have options even if your measurement seems high.

Common mistake: Measuring the underbust too loosely. Pull the tape so it lies flat and level—this gives you the actual size the fabric needs to cover.

Step 3: Measure Your High Hip

The high hip is the widest part of your lower torso, usually about 3 to 4 inches below your waist, at the top of your hip bones. Wrap the tape around this area, keeping it parallel to the floor. This measurement is crucial for determining whether a corset will sit comfortably over your hips without digging in or riding up.

Corsets with a larger hip spring—like the Artemis Corset Designed by Lucy’s Corsetry, which features a high hip of 12 inches—are made to accommodate curvier figures. If your high hip measurement is significantly larger than your waist, look for a corset with a generous hip spring, or choose one designed to sit over the hips rather than above them.

Checkpoint: Your hip measurement should be taken at the point where your torso meets your leg, but not over your thigh—that’s too low.

How to Use Your Measurements with a Corset Size Chart

Once you have your three numbers, you’re ready to find your corset size. Most size charts list corset sizes in terms of the waist reduction (for example, 6 inches smaller than your natural waist) and the underbust and hip circumference at the corset’s top and bottom edges. For a typical training corset, you want the corset’s underbust to be about 1 inch larger than your underbust measurement, and the hip to be about 1 to 2 inches larger than your high hip, to allow for breathing and movement.

If you’re between sizes, size up rather than down—a corset that’s too tight will hurt and may cause damage. Many brands, including High Quality Corsets, offer sizing guidance on their product pages; when in doubt, refer to the specific corset’s measurements, as designs vary. For instance, the Playgirl Faith 24 Steel Boned White Waist Training Corset is designed to take 6-7 inches off the waist, which is more aggressive than a typical starter corset.

Remember: always read the product’s individual size chart. A corset’s underbust and hip measurements are just as important as the waist size—skipping them leads to ill-fitting pieces that gap at the top or dig into your hips.

• Compare your underbust and hip to the corset’s listed top and bottom measurements—not just the waist.
• If you have a longer torso, check the front length of the corset; short-waisted styles like the Playgirl Minnie Sapphire Blue Steel Boned Waspie Corset focus the pull on your waist.

Your Corset Measuring Routine in 5 Steps

1. Find your natural waist: Bend side to side to locate the crease, then wrap the tape around that point, keeping it parallel and snug. Checkpoint: Breathe normally—don’t suck in.
2. Record your underbust: Wrap the tape directly under your bust, level around your ribcage. Checkpoint: The tape should be snug but not squeeze.
3. Measure your high hip: Place the tape about 3-4 inches below your waist, over the top of your hip bones. Checkpoint: Keep the tape level—don’t let it twist.
4. Check the size chart: Compare all three measurements against the corset’s listed underbust, waist, and hip circumferences. Verdict: If between sizes, size up for comfort.
5. Confirm the corset length: Verify that the front and back lengths suit your torso height. Takeaway: Short-waisted? A waspie style may fit better.

Products That Fit Real Measurements

• Plus Size Artemis Hourglass Silhouette Corset in Black Mesh: The Artemis Corset features a dramatic hourglass curve and shows off a rib spring of 8" and a high hip of 12". The high back prevents muffin-top while the cupped rib adds extra comfort in the front. If your underbust-to-waist difference is around 8 inches and your high hip is around 12 inches, this corset is designed to accommodate your curve without gaping.
• Playgirl Eve Steel Boned Dragon Brocade Cincher: The chinese dragon brocade waist cincher has 10 steel bones (6 spiral and 4 flat), a front busk closure, and is 10 inches long at both front and back. This cincher is a good option if your measurements fall on the shorter side—its 10-inch length targets your waist without covering your ribs or hips.
• Artemis Corset Designed by Lucy's Corsetry Hourglass Silhouette in Black: The Artemis Corset features a dramatic hourglass curve and shows off a rib spring of 8" and a high hip of 12". The high back prevents muffin-top while the cupped rib adds extra comfort in the front. Measuring your underbust and high hip with this corset’s specs in mind helps you see whether you need a style with a pronounced rib spring and hip spring for a smooth line.

Measuring for a corset doesn’t have to be complicated. Take your natural waist, underbust, and high hip, then use those numbers to read the size chart—not the dress size. When you start with accurate measurements, you’ll know whether a dramatic curve like the Artemis or a focused cincher like the Eve is right for you. And remember, when in doubt, go a little roomier; you can always adjust with the laces, but you can’t add fabric that isn’t there.
