How to Find Your Perfect Nipple Cover Size (UMI’s Guide & Size Chart)

Why Finding the Right Nipple Cover Size Is Harder Than It Should Be

Let’s be real — figuring out how to find your perfect nipple cover size used to drive me absolutely crazy. I’d order what I thought was my nipple cover size, only to have them either barely cover anything or create weird bumps under my favorite tops. Every brand seemed to have different labels—S, M, L—and the nipple covers size chart never matched what actually showed up in the mail.

After way too many trial-and-error purchases (and a few wardrobe malfunctions), I finally cracked the code. Now I know exactly how to find your perfect nipple cover size, and I’m sharing everything I learned so you don’t have to waste money like I did. Whether you’re looking for silicone nipple covers size guidance or need a real nipple covers size comparison between brands, this guide has you covered—literally.

Promise: This guide (with a real nipple cover size chart in cm and inches) will help you find your perfect fit — from A cups to larger cup sizes like DD and 36DDD breasts.

Why Getting the Right Nipple Cover Size Actually Matters

Understanding the Impact of Proper Sizing

Here’s what I wish someone had told me from the start: nipple cover size isn’t just about your bra cup size. It’s about comfort, invisibility, and confidence all rolled into one.

When I wore silicone nipple covers that were too small, they’d irritate my skin and leave visible edges under fitted shirts. Too large? They’d wrinkle at the edges or create an unnatural shape that defeated the whole purpose of wearing them.

Three Key Reasons Size Matters

Comfort: Too small and they dig in, especially if you have sensitive skin. Too large, and they shift around all day. The right nipple cover size makes you forget you’re wearing anything at all.

Invisible Fit: The wrong size shows through clothing—either as visible edges or weird lumps. Whether you’re choosing invisible nipple covers for a backless dress or reusable, seamless nipple covers for everyday wear, the right size makes all the difference.

Hold and Confidence: Properly sized covers stay in place, whether you have a C-cup breast size or larger cup sizes like 34E breasts or 36DDD breasts. Nothing kills your confidence faster than feeling your covers slide during an important moment.

Measure your nipple size with a soft measuring tape

Finding the Right Nipple Cover Size means measuring your nipple, not your areola.

Step 1 — Measure Your Nipple Diameter at Home (Accurate & Easy)

How to know what size nipple cover to get?

Finding your nipple size is the secret to choosing the right nipple cover size. I know it sounds awkward, but trust me—this 5-minute measurement will save you from so many returns. Your actual nipple size matters more than your bra size when it comes to proper coverage.

Method 1: The Ruler Method

This is my go-to method because it’s quick and accurate. Stand in front of a mirror (good lighting helps!) and hold a ruler or measuring tape horizontally across the widest part of your nipple—not the areola, just the actual nipple.

Key insight: If your nipple size measures around 1 inch (or about 2.5 cm), you’ll likely need nipple covers small in the 7–8 cm range. If you’re measuring closer to 1.5 inches, you’re looking at nipple covers 4 inch to 5 inch sizes for proper coverage.

Method 2: Coin or Card Comparison

Don’t have a ruler handy? Grab a quarter (which is about 1 inch in diameter) or a credit card (about 3.37 inches wide). Hold it next to your nipple and compare.

This quick trick is perfect for figuring out whether you need nipple covers 3 inch, nipple covers 4 inch, or nipple covers 5 inch sizes. A quarter is roughly the size of a small nipple, so if yours is significantly larger, you’ll want to size up.

Method 3: Paper Tracing

For those with irregular shapes (totally normal, by the way), place a piece of paper against your skin and gently trace around your nipple with a pencil. Then measure the widest part of your tracing. This method gives you the most accurate nipple size measurement for unusual shapes.

Method 4: String & Circle Formula

This one’s for my detail-oriented friends. Take a piece of string and wrap it gently around your nipple to measure the circumference. Then divide that number by 3.14 (π) to get your diameter.

If your result is around 4 inches, you’re in the pasties, large or nipple covers for large nipples category. For fuller busts like 36G boobs, 38DDD tits, or L cup breasts, this precision really matters for comfort.

Pro Tips for Accurate Measurement

Double-check your measurements: Use two different methods to confirm your measurement. I always double-check because even a small difference affects how your silicone nipple covers size will fit.

Consider your breast size context: While nipple size is the primary factor, knowing whether you have 34E breasts, DDD boobs, or B cup breast size helps with the final nipple cover size comparison.

Step 2 — Understand the U.S. & UMI Nipple Covers Size Chart (in cm + inches)

General U.S. Sizing Standards

Once I understood the nipple cover size chart, everything clicked. Here’s a general nipple size chart that most U.S. brands follow:

Why Understanding Both cm and Inches Matters

Understanding nipple cover size in cm as well as inches is crucial because different brands use different measurements. When I finally looked at both, I realized why my previous orders never fit—I was mixing up the units!

This silicone nipple covers size reference helped me understand that just because I wear a certain cup size doesn’t automatically determine my nipple covers size. Your actual nipple size matters more than your bra size when it comes to proper coverage.

Step 3 — Match Your Measurement to the UMI Official Silicone Nipple Covers Size Chart

UMI’s Comprehensive Sizing System

Now let’s talk about UMI’s specific sizing, which is honestly the most comprehensive nipple cover size comparison I’ve found. Here’s their official chart:

Real-World Application Examples

What I love about UMI’s approach is that they give you both the cup reference AND the actual diameter. This nipple covers size comparison makes it so much easier to match your measurement to the right product.

For example, I have 34E breasts, and Size 2 works perfectly for me. My friend with 36DDD boobs swears by Size 4 because it gives her the full coverage she needs without any shifting throughout the day.

Material Quality and Sizing Flexibility

The silicone nipple cover material also matters here. UMI uses medical-grade silicone that’s flexible enough to mold to your natural shape, which means even if you’re between sizes, they’ll still look like invisible nipple covers seamless.

Visual Size Comparison Guide

Let’s do a quick nipple covers size comparison to visualize coverage:

• Nipple covers 3 inch: ideal for smaller chests (A–C cups), natural look
• Nipple covers 4 inch: great for D+ cups, smooth coverage
• Nipple covers 5 inch: works best for DD+ cups or fuller shapes
• Nipple covers 6 inch: for large nipple covers needs, especially DDD+ cups or 36G–38DDD breasts

This side-by-side view helps ensure your silicone nipple covers size matches both your cup and nipple diameter—because comfort and invisibility depend on both.

Step 4 — Common Sizing Questions (Real Answers)

Question: I’m Between Two Sizes — What Should I Do?

Answer: Go one size up! Seriously, I learned this the hard way. When I was stuck between nipple covers 4 inch and nipple covers 5 inches, I went smaller, thinking it would look more natural. Wrong. The larger size actually gave me better coverage AND looked more invisible because there were no visible edges.

If you’re debating between Size 2 and Size 3, choose Size 3. Better to have a little extra coverage than not enough. The reusable seamless nipple covers from UMI are designed with ultra-thin edges, so even larger sizes blend beautifully.

Question: Does My Outfit Affect Which Nipple Covers Size I Need?

Answer: Yes! This was a game-changer for me. Different outfits call for different considerations:

Tight tops or bodycon dresses: You want invisible nipple covers with smooth edges. Use your true nipple cover size measurement and don’t size down, thinking smaller will be less visible. The opposite is true!

Backless or strapless dresses: Silicone nipple covers work best here for that natural shape. Stick with your measured nipple covers size chart recommendation because these need to stay put without any bra support.

Everyday wear under T-shirts: Go with your true fit using the nipple size chart as your base. Comfort is key for all-day wear.

Sheer or thin fabrics: Consider sizing up slightly for maximum coverage and confidence. Nobody wants to worry about show-through.

Question: What If I Have Larger Nipples or Larger Cup Sizes?

Answer: Trust me, I have friends with larger cup sizes like DDD tits and 34G breasts who struggled with this. The solution? Try nipple covers for large nipples or pasties large—UMI’s Size 3 or 4 work amazingly well.

For 34H breasts, 36G boobs, OG double D sizes, or even add 2 cup sizes bra situations, the nipple covers 6 inch diameter of Size 4 provides that full, confident coverage you need. Don’t settle for smaller sizes that leave you constantly adjusting. The right large nipple covers should make you forget you’re even wearing them.

Question: How Do I Know If My Measurement Is Accurate?

Answer: Use multiple measurement methods and compare results. If you get consistent readings across two different methods (like the ruler method and coin comparison), you can trust your nipple size measurement. This accuracy is crucial for finding your perfect nipple cover size.

Step 5 — Quick Recap: The 3-Step Formula for the Perfect Fit

Your Simple Three-Step Process

After all my trial and error, I’ve boiled down how to find your perfect nipple cover size down to three simple steps:

• Step 1: Measure your nipple size accurately (in inches or cm) using one of the methods above.
• Step 2: Compare your measurement to this nipple cover size chart to find your range.
• Step 3: Match your result to the UMI silicone nipple covers size chart. When in doubt between two sizes, always size up for better coverage and comfort.

Why This Formula Works for Everyone

This formula works whether you’re an A cup or rocking 38DDD tits. The key is focusing on your actual nipple size, not just your bra size. Once I stopped assuming my cup size determined my nipple covers size, everything fell into place.

Understanding the nipple covers size comparison between your measurements and the chart takes the guesswork out of online shopping. No more returns, no more disappointment—just the perfect silicone nipple covers size on your first try.
