Your Recommended Bridal Size
Wedding Dress Size Chart UK, USA, Canada, Australia, Europe
So, you got your numbers from the bridal size calculator in inches above. But what happens if you live in New York, and your absolute dream designer is based in London or Milan? Bridal fashion is a global industry, which means you are going to encounter a lot of international labels while dress hunting.
A size 10 in America is vastly different from a size 10 in the United Kingdom or Australia. If you accidentally order a US 10 from an Australian designer, you are going to receive a dress that is drastically too small. To help you shop online or understand international designer tags, we’ve put together this comprehensive global comparison chart.
| Bust (In.) | Waist (In.) | Hips (In.) | US / Canada Size | UK / AUS Size | Europe (EU) |
|---|---|---|---|---|---|
| 32 | 24 | 35 | 0 | 4 | 30 |
| 33 | 25 | 36 | 2 | 6 | 32 |
| 34 | 26 | 37 | 4 | 8 | 34 |
| 35 | 27 | 38 | 6 | 10 | 36 |
| 36 | 28 | 39 | 8 | 12 | 38 |
| 37.5 | 29.5 | 40.5 | 10 | 14 | 40 |
| 39 | 31 | 42 | 12 | 16 | 42 |
| 40.5 | 32.5 | 43.5 | 14 | 18 | 44 |
| 42 | 34 | 45 | 16 | 20 | 46 |
| 44 | 36 | 47 | 18 | 22 | 48 |
| 46 | 38 | 49 | 20 | 24 | 50 |
| 48 | 40 | 51 | 22 | 26 | 52 |
| 50 | 42 | 53 | 24 | 28 | 54 |
| 52 | 44 | 55 | 26 | 30 | 56 |
✨ A Quick Rule of Thumb
If you ever forget the chart, just remember this math: Add 4 to your US size to get your UK/Australian size. Add 30 to your US size to get your European size. (Example: A US size 8 + 4 = UK Size 12!). Always check with the specific designer, but this trick works 95% of the time.
Wedding Dress Sizing Chart Vs Street Size
Let's talk about the elephant in the bridal suite. Almost every single bride experiences the "fitting room freakout." It usually goes exactly like this:
You wear a comfortable size 6 or 8 from your favorite mall brand (think Zara, H&M, or Gap). You step into the bridal boutique feeling great, the consultant wraps a soft measuring tape around you, does some quick math, and gently tells you, "Okay, we'll be ordering you a bridal size 14."
Wait, what? A 14? Your heart drops. Did you measure wrong? Is the mirror lying to you? The answer is a loud, emphatic NO. Your body is perfect. The confusion comes down to something called vanity sizing.
The Truth Behind the Tag
Over the past forty years, standard ready-to-wear clothing brands have gradually changed their sizing to make consumers feel better. A pair of size 6 jeans today is physically much larger than a size 6 pair of jeans from 1980. This is vanity sizing.
But the bridal fashion industry? They mostly refused to participate. High-end wedding dress designers build their gowns using traditional, historical European pattern blocks that haven't changed in decades. Because these bridal size charts have remained static while "street sizes" got larger, there is a massive gap today. When comparing a wedding dress sizing chart vs street size, expect your bridal dress to be roughly one to two full sizes larger than your normal clothes.
Bridal Size Calculator In Inches
If you have spent any time browsing designer websites or chatting with boutique consultants, you have probably noticed that everything revolves around inches. But why? Why can't we just use a standard small, medium, or large?
A wedding gown is a highly structured, architectural garment. It is often built with intricate boning, corsetry, and tightly woven non-stretch fabrics like Mikado silk, taffeta, or heavy crepe. Because there is absolutely zero "give" in these luxurious materials, precision is everything. An inch too small, and the zipper simply won't budge.
Our bridal size calculator in inches is engineered to mimic the exact sizing formulas used by professional seamstresses and luxury bridal houses worldwide. By entering your raw measurements in inches, this tool completely bypasses the confusing world of everyday clothing sizes. It matches your unique body shape directly to the designer's pattern blocks, ensuring you get a mathematically accurate recommendation. This is the absolute best way to know your true bridal size before you ever step foot into a boutique.
How To Measure Properly
If you put bad numbers into our calculator, you're going to get a bad result. Measuring yourself correctly is the single most important step in this process. Have your fiancé, your mom, or your maid of honor help you—it's very hard to do it perfectly by yourself.
Your Step-by-Step Measurement Guide
Before you begin, grab a soft, flexible cloth tape measure (not metal!) and wear the exact undergarments you plan to wear on your wedding day.
1. The Bust
Wrap the tape under your arms, flat across your back shoulder blades, and over the absolute fullest part of your bust (usually right across the nipples). Keep the tape parallel to the floor.
2. The Waist
Find your natural waist (the narrowest part of your torso, typically 1 to 2 inches above your belly button). Wrap the tape around comfortably—don't suck in!
3. The Hips
Stand straight with your heels touching. Measure around the fullest, widest part of your hips and bottom. This sits about 7 to 9 inches below your natural waistline.
4. Hollow to Floor
Stand barefoot. Find the "hollow" at the base of your neck. Run the tape straight down from that point to the floor to dictate your dress skirt length.
Wedding Dress Size Calculator By Height And Weight: Why It’s A Myth
One of the most common questions brides ask us is, "Can't I just use a wedding dress size calculator by height and weight?"
It's tempting because it sounds so easy, but the definitive answer from professional bridal stylists is: Absolutely not. Height and weight cannot determine your wedding dress size, and attempting to do so will almost guarantee you order the wrong gown.
The Apple vs. Pear Dilemma
Let's look at a real-world example to explain why weight is a useless metric for a bridal size chart. Imagine two brides who both weigh exactly 155 pounds and are both 5'6" tall.
Bride A has a classic "pear" shape. She has delicate, narrow shoulders, a small bust, and carries most of her weight in her hips and thighs. Bride B has an athletic "inverted triangle" shape. She has broad swimmer's shoulders, a larger bust, but very narrow, slender hips.
Despite having the exact same height and weight on the doctor's scale, they are going to need radically different dresses. Bride A will likely need to order a size 14 to accommodate her hips, with a seamstress taking the bodice in extensively. Bride B might need a size 14 to fit her bust and back, while the seamstress takes the skirt in drastically around her hips. If either of them relied on a generic height/weight calculator, they would end up with a dress that simply won't zip up.
A wedding gown is a highly structured, architectural garment with zero stretch. It doesn't care what you weigh; it only cares about your physical inches. That is why our bridal size calculator in inches is the only accurate way to predict your tag size!
Frequently Asked Questions
How Many Sizes Do You Go Up In A Wedding Dress?
As a general rule, you should expect to go up one to two full sizes from your normal everyday clothing (street size). However, instead of just guessing or sizing up blindly, you should always take your exact measurements in inches and compare them to the specific designer's size chart, as every bridal brand cuts differently.
Why Are Wedding Dresses 2 Sizes Smaller?
Wedding dresses are based on traditional European sizing charts from the 1950s. While everyday clothing brands have adjusted their sizes over the decades to make consumers feel better (called "vanity sizing"), bridal designers have largely kept the original, historical measurements intact. This causes a massive gap between your street size and bridal size.
What Size Wedding Dress Am I If I Am A Size 8?
If you comfortably wear a street size 8 in standard ready-to-wear brands, you will likely be a size 10 or 12 in bridal sizing. The exact size will ultimately depend on your individual bust, waist, and hip measurements in inches, as well as the silhouette of the dress (e.g., ballgown vs. fitted mermaid).
How Do I Calculate My Wedding Dress Size?
To accurately calculate your bridal size, use a soft measuring tape to find your bust, natural waist, and hip measurements in inches. Then, compare those numbers to a bridal size chart. You must always order the size that corresponds to your largest measurement. Our calculator above does all of this math for you instantly.
Can A Wedding Dress Be Taken In 2 Sizes?
Yes! A skilled bridal seamstress can typically take in a structured wedding dress by up to two to three full dress sizes without altering the original design or structural integrity of the gown. This is exactly why stylists tell you to order a dress that fits your largest measurement—taking a dress in is easy, but letting a dress out is often impossible.
What Real Brides Are Saying
Saved me a panic attack in the dressing room!
"I’m a street size 6, so when the boutique told me they were ordering a size 12, I honestly wanted to cry. I came home and used this calculator. The tip explaining why my hip measurements pushed me to a 12 made total sense. Such a relief to know there’s nothing wrong with my body, the industry is just crazy!"
Perfect for buying off StillWhite
"I was buying a second-hand dress online from a bride in Australia and had ZERO clue how their sizing worked. The international chart on this page gave me the confidence to buy it. The dress arrived last week and it zipped up perfectly!"
Great catch on the length!
"I absolutely love that this calculator asks for your hollow-to-floor measurement. I’m 5’10” and the tool warned me I might need extra length. I asked my bridal salon about it the next day, and they confirmed I did! I would have had a high-water dress without this."
Accurate and super easy
"Very straightforward. I measured myself three times just to be paranoid, plugged the numbers in, and it told me I was a 14. Went to my first bridal appointment today and the sample size 14 fit me like a glove. Highly recommend doing this before you shop so you aren't blindsided."
Finally, someone explains it clearly
"The rule about ordering for your largest measurement is brilliant. I have broad shoulders and a large bust but a tiny waist. This explained exactly why I have to order a 10 even though my waist is a 4. Thank you for this!"
Mythbusters for brides!
"I was frantically searching for a height and weight calculator and found this article instead. Reading the part about the 'Apple vs Pear' shape made me realize how stupid a weight-based calculator is. Measured my inches instead and got the right size."
