How do I choose the right sunglasses size?

Choosing the right sunglasses size might sound simple, but when you actually start shopping—especially online—it can feel confusing. Frames look great in photos but might feel too tight, too loose, or sit awkwardly on your face in reality. Whether you’re buying stylish goggles for daily wear, sporty goggles for outdoor activities, or bold fashion goggles to upgrade your personality, size matters more than you think.

The right sunglasses size not only affects comfort but also impacts how confidently you carry the look. At goglassic.com, we believe that goggles should give you both style and comfort. That’s why understanding size is the first step to choosing the perfect pair.

In this complete guide, you’ll learn exactly how to measure your face, how goggles sizes work, how to read frame measurements, and how to match goggles size to your face shape. By the end, you’ll be able to pick the right sunglasses size confidently every single time.

Why Choosing the Right Goggles Size Is So Important

When you wear goggles that fit perfectly, several things happen:

✔ Comfort Improves

Goggles that fit well sit comfortably on your nose and ears without squeezing or slipping.

✔ Protection Increases

A proper size ensures your eyes receive maximum UV and glare protection.

✔ Style Enhances

Even the best goggles look odd when they’re too large or too small. Size influences how balanced and attractive the goggles appear on your face.

✔ Performance Boosts

Especially for sports goggles, the correct size prevents movement during cycling, running, or outdoor work.

Choosing the correct sunglasses size is not just about aesthetics—it’s equally about comfort, safety, and vision clarity.

How to Measure Your Face for the Right Sunglasses Size

The easiest way to choose the right goggles size is by understanding your face measurements. Here are three simple measurements you can take at home:

1. Measure Your Face Width

This is the most important measurement.

  • Stand in front of a mirror.

  • Take a measuring tape.

  • Measure from the left temple to the right temple.

Face Width Guide:

Face Width Ideal Goggles Size
110–125 mm Small
125–140 mm Medium
140–150 mm Large
150 mm+ Extra Large

Most people fall in the medium category, which is why many goggles are designed to fit medium-width faces.

2. Measure Your Pupillary Distance (PD)

PD = the distance between your pupils.

It helps ensure your goggles align correctly with your eyes.

Typical PD ranges:

  • Women: 58–62 mm

  • Men: 60–66 mm

This matters mainly for prescription goggles, but knowing it helps ensure your sunglasses lenses align well with your vision zone.

3. Measure Your Nose Bridge Width

Your nose bridge plays a major role in how comfortably goggles sit.

If goggles slide down or pinch your nose, the bridge size is incorrect.

Understanding Sunglasses & Goggles Measurements

When you look at goggles online, you’ll often see numbers like:

52 □ 18 – 140

These numbers represent:

1. Lens Width (52 mm)

The width of each lens.
Affects coverage and how big the goggles appear.

2. Bridge Width (18 mm)

Distance between the two lenses.
Controls how goggles sit on your nose.

3. Temple Length (140 mm)

Length of the goggles’ arms.
Controls comfort behind your ears.

Let’s break them down further:

Lens Width

  • Small: 48–52 mm

  • Medium: 53–58 mm

  • Large: 58+ mm

If you want oversized goggles (a trending fashion look), go for a larger lens width.
If you want a minimal, sharp look, choose smaller lens widths.

Bridge Width

  • Narrow: 14–16 mm

  • Medium: 17–18 mm

  • Wide: 19–23 mm

A correct bridge width ensures your goggles stay in place without sliding.

Temple Length

  • Standard: 135–145 mm

  • Long: 150+ mm

If goggles press behind your ears, the temple length might be short for you.

How to Know If Your Goggles Fit Perfectly

Before buying, check these signs:

✔ The goggles don’t touch your eyebrows.

If they do, they’re too big.

✔ They don’t slide down your nose.

If they slide, either the frame or bridge is too large.

✔ Your eyelashes don’t touch the lenses.

If they do, the goggles are too small.

✔ The temples don’t pinch behind your ears.

If they do, temple length may be short.

✔ The goggles sit comfortably for 10+ minutes.

This is the real test of comfort.

How to Choose the Right Goggles Size Online (Especially on goglassic.com)

Buying goggles online is easier when you follow these steps:

1. Check the Product Size Chart

Most goggles on goglassic.com clearly mention lens width, bridge width, and temple length. Match these with your measurements.

2. Compare With Your Existing Goggles

If you have a pair you love, check the size numbers printed on the inner side of the temples. Choose a similar size online.

3. Look for “Universal Fit” or “Medium Fit” Tags

These are designed to comfortably fit most face shapes and sizes.

4. Choose Goggles Based on Occasion

● Daily Wear Goggles

Medium size fits most people comfortably.

● Driving Goggles

Wider lenses (55–60 mm) help reduce glare and improve coverage.

● Sports Goggles

Snug-fit design with a secure grip works best.

● Fashion Goggles

Oversized or bold frames give a powerful style statement.

Common Mistakes People Make While Choosing Goggles Size

❌ Choosing goggles just because they look good

Size and comfort are equally important.

❌ Ignoring bridge width

This leads to constant slipping or pressure on the nose.

❌ Buying oversized goggles for every face

Oversized looks good only when it suits the face width.

❌ Not checking temple length

This causes discomfort and headaches.

Pro Tips for Picking the Perfect Goggles Size

✔ Choose goggles that match your face width

Ask yourself: Do the frames extend past the temples? If yes, they’re too big.

✔ Try mid-sized frames if unsure

Medium goggles fit 80% of people.

✔ For men

54–58 mm lens width usually works best.

✔ For women

50–55 mm lens width works for most face shapes.

✔ For teenagers

48–52 mm lens width is ideal.
