How To Measure Women’s Dresses

Measuring for a dress is slightly more detailed than other garments. This is how to get accurate measurements:

1. Bust Measurement: Measure around the fullest part of your bust while keeping the tape parallel to the floor.
2. Waist Measurement: Measure around the narrowest part of your waist, ensuring the tape remains parallel to the floor.
3. Hip Measurement: Measure around the fullest part of your hips, keeping the tape parallel to the floor.
4. Shoulder Measurement: Measure from one shoulder tip, across your back, to the other shoulder tip.
5. Torso Measurement: Measure from the top of your shoulder to the desired length of the dress.
6. Sleeve Length: Measure from the top of your shoulder down your arm to the desired sleeve length.

Compare your measurements to the appropriate dress size chart to ensure you get the best fit.

How To Measure Yourself for the Perfect Fitting Bra

A well-fitting bra is a game-changer, and finding your perfect fit is all about getting accurate measurements. Here’s a bra measurement guide: 

1. Under-Bust Measurement: Measure around your ribcage, just under your bust. Round up to the nearest whole number.
   1. For example, if you get a measurement of 33.5 inches, round it up to 34 inches.
2. Band Size: After rounding, if the number is even, add 4 inches; if it’s odd, add 5 inches.
   1. For example, if the measured under-bust is 29 inches, your band size is 34.
3. Bust Measurement: Measure around the fullest part of your bust and round to the nearest whole number.
4. Cup Size: Subtract your band measurement from your bust measurement. The difference determines your cup size.

It’s a good idea to know your measurements, whether you’re shopping locally or internationally. Using the size conversion charts above helps you get the best size anywhere in the world, including at home. 

Men’s International Clothing Size Chart​

When shopping for men’s clothing across different countries, knowing your exact size in various global systems gives you the confidence to shop from international retailers so you always find a great fit. These international men’s clothing size charts are separated by type: men’s tops (shirts, dress shirts, jackets, blazers, and coats) and bottoms (pants, trousers, dress pants, and shorts) to make it easier to convert sizing. 

International Size Conversion Chart for Men’s Tops (Shirts, T-Shirts, Jackets, Blazers, Coats)

As a general rule, men’s sizing tends to be more standardized globally. Men’s clothing doesn’t have as much variation in style or cut compared to women’s clothing, so many countries use a similar approach to sizing. This men’s international clothing size conversion chart has the details, including sizing in inches and centimeters. 

Alpha Sizes	US	UK	Europe	Russia	Japan	Korea
XXS	30	30	40	40	32	80

Global Size Conversion Chart for Men’s Pants, Jeans, and Bottoms

For men’s pants, international clothing size charts usually feature U.S. and European sizing, as these two systems are widely recognized and used. They’re generally the most common point of comparison. Other sizing charts, like in Japan, correlate to waist circumference in centimeters rather than inches. 

Keep in mind that most retailers use the same size conversion chart for men’s pants, but it’s best to check with the specific retailer to confirm their size conversion chart.

US	Europe	Japan
30	46	76
32	48	80
34	50	84
36	52	88
38	54	92
40	56	96
42	58	100

How To Measure Men’s Clothing Size

To get your correct measurements for men’s clothing, you’ll need a tape measure and a bit of time to ensure accuracy. Below is what to measure:

• Chest: Measure around the fullest part of your chest, keeping the tape measure parallel to the floor.
• Waist: Measure around the narrowest part of your waist, keeping the tape measure parallel to the floor.
• Torso Length: Measure from the highest part of the collar (on a shirt or jacket) straight down to where the garment ends.
• Neck Size: For dress shirts, measure around the base of your neck, just above your collarbone, making sure the tape is snug but not tight, allowing you to fit a finger between the tape and your neck.
• Inseam Length: For pants, measure from the top of your inside leg at the crotch to the bottom of your ankle.

Kids’ International Size Conversion Charts

Kids’ sizing is generally the same for girls’ and boys’ sizes until they hit the teenage years. Finding the right size wherever you shop is a critical process, allowing your children to move freely and comfortably in whatever they are wearing. Here is an in-depth children’s international clothing size chart guide.

International Clothing Size Chart: Children’s Clothing

These sizes apply to all kids as they grow, but with a few things to note: 

• Sizing for kids under 12 usually aligns with age (e.g., 3T, 4T, 5/6, etc.) or height. 
• Sizing for older kids may align more with general clothing size (Small, Medium, Large).
• Because every child is different, your child’s age may not correlate directly with the clothing sizes below.
• Toddler sizes are generally used for children ages 2-5, and infant sizes are used for children younger than 2 years old. 
• In some cases, boys’ sizes may be slightly bigger, especially as kids get older.

The sizes are typically labeled on the clothing tags or product description, with measurements in the retailer’s sizing guide to make sure you choose the right fit. If you’re unsure of your child’s size, measuring their chest, waist, and height can help you avoid the potential discrepancies that come with age-based sizing. 

Use this global size conversion chart to find the children’s clothing size you need.

US (Age-Based)	UK (Age-Based)	European	Australian
Newborn	50 cm	Newborn	00000

How to Measure Children’s T-Shirt Size

T-shirt size is usually considered a general clothing size in conversion charts for kids. This step-by-step guide helps you measure T-shirt size to help you make the best sizing choice for your child:

• Lay the T-shirt Flat: Start by laying your child’s existing, well-fitting T-shirt on a flat surface. Make sure there are no wrinkles or folds in the fabric for an accurate measurement.
• Measure the Torso Length: Using a measuring tape, measure from the highest point of the shoulder (where the seam meets the collar) straight down to the bottom hem of the shirt. 
• Measure the Sleeve Length: For a proper sleeve fit, measure from the seam at the top of the shoulder (where the sleeve seam meets the body of the shirt), along the sleeve, to the end of the cuff. 
• Measure Across the Chest: To measure the chest, place the tape measure across the T-shirt from armpit to armpit. 

Keep in mind that using age, height, or chest size for T-shirts often matches the general kids’ clothing size conversions, but you might also need to consider other types of measurements, such as waist, length, etc., depending on the clothing category.

International Size Conversion Chart for Kids’ Pants, Jeans, and Bottoms

Kids grow at different rates, so shopping for pants, jeans, and other bottoms often involves slightly different considerations than general clothing size. Kids’ pants sizing can vary between brands, so it’s always a good idea to measure your child’s waist, hips, and inseam for a more accurate fit. 

This international clothing size chart​ offers a solid frame of reference for children’s pant size.

Tips for Measuring Children’s Pant Size

Height is the most reliable measurement for kids’ pants and will give you the most accurate idea of which size fits best in any system. Here are the most important measurements to size correctly: 

• Waist Measurement: Use a soft measuring tape to measure around your child’s waist, just above the hips.
• Inseam: Measure from the crotch to the bottom of the ankle to find the correct pant length.
• Height: Measure your child standing straight, from the top of the head to the floor.

Also, consider your child’s typical weight range, as this often helps with ensuring the fit of pants and jeans.

How To Measure a Kid’s Feet for Perfect-Fitting Shoes

When it comes to navigating international kids’ shoe sizes, getting the right fit is more than a matter of style—it’s critical for their comfort and foot development. Here are the steps to measure your kid’s feet:

1. Prepare: Place a piece of paper on the floor and have your child stand with their heel against a wall.
2. Trace: Use a pencil to trace around the foot, ensuring the pencil is upright.
3. Measure: Measure the distance from the longest toe to the heel of the traced foot.
4. Repeat: Measure the other foot, as it may be slightly larger.
5. Width: To measure the width, measure across the widest part of the traced foot.

Use the appropriate shoe size chart to match the measurements to the correct size, keeping in mind that it may not correlate with your child’s age or clothing size category.
