How to Find Your Ideal Ray-Ban Sunglasses Size Before You Buy

To find your ideal Ray-Ban sunglasses size, start with the measurements of a pair that already fits comfortably. Compare its lens width, bridge width and arm length with the exact model you want, then check the bridge design and overall frame proportions.

A 50 mm lens in one style does not guarantee the same fit as a 50 mm lens in another. Use the steps below to narrow down your size before ordering.

Read the measurements inside your current frames

Look inside the arms of your glasses or sunglasses for three measurements, usually printed in millimetres. A size marking such as 51 □ 18 145 breaks down like this:

The square symbol separates the lens and bridge measurements. Keep the model code too: RB2132 identifies the New Wayfarer, for example, rather than its size.

On Ardor Eyewear’s Ray-Ban New Wayfarer RB2132 page, the displayed 51 mm version has an 18 mm bridge and 145 mm temples. That gives you three useful comparison points instead of one.

Measure a comfortable pair if the numbers have faded

Use a ruler marked in millimetres and work in good light. Measure one lens horizontally at its widest point, excluding the surrounding rim. For a rough bridge measurement, measure the shortest horizontal gap between the lenses.

Also measure the full frame front straight across, from its outermost left edge to its outermost right edge. Note that separately as overall frame width. Ask the retailer for the equivalent measurement if it is missing from the product page.

Do not calculate overall width simply by doubling lens width and adding the bridge. That leaves out parts of the rims and the sections extending towards the hinges.

Temple length follows the arm towards its curved tip; a straight measurement between its endpoints can underestimate it. Use the printed figure wherever possible.

If you have no suitable pair, try frames at an optician and record the model and size that feel comfortable. This gives you a more useful starting point than guessing from a selfie.

Compare sizes within the exact Ray-Ban model

Treat each model as a separate fitting decision. Ardor Eyewear lists the following lens-width options:

These are listed options, so check availability for your chosen colour and lens combination.

The displayed 50 mm Original Wayfarer has a 22 mm bridge and 150 mm temples, whereas the 51 mm New Wayfarer has an 18 mm bridge and 145 mm temples. Their similar lens widths conceal quite different measurements elsewhere.

The displayed 55 mm Aviator has a 14 mm bridge and 135 mm temples. Its metal construction and nose pads also change how it sits compared with a moulded bridge.

Use labels such as small, medium and large to shortlist frames, then compare the actual dimensions. Avoid treating any lens width as a universal size across the collection.

Check how the bridge supports your nose

Bridge width is only part of the fit. The shape of the bridge and its contact points determine where the sunglasses rest.

If moulded bridges usually sit comfortably on you, a similar design is a sensible starting point. The New Wayfarer and Original Wayfarer versions above are listed as high bridge fit, intended for a higher nose bridge and lower cheekbones. If your current sunglasses slide or touch your cheeks, ask about a different bridge design before automatically choosing a smaller lens.

Adjustable nose pads offer another option. Ardor Eyewear lists the Ray-Ban Clubmaster RB3016 with adjustable nose pads, allowing the contact points to be tailored to your nose. An optician can assess and adjust them.

Adjustment can refine a suitable frame’s fit, but it should not be your plan for making a substantially wrong size work.

Test the fit while moving

When you can try the intended model before buying, leave it on for several minutes. Check the following:

• At your temples: the arms should sit comfortably without squeezing the sides of your head.

• At your nose: the frame should feel supported without pinching or repeatedly slipping.

• At your cheeks: smile normally; the lower rims should not be pushed upwards by your cheeks.

• At your eyes: blink naturally and check that your eyelashes clear the lenses.

• Behind your ears: the arms should feel secure without digging in.

Look down and turn your head gently. A pair that needs constant repositioning deserves another look at its size or bridge fit. Ardor Eyewear’s sunglasses fitting advice also emphasises stability, comfortable contact points and cheek clearance.

Confirm the selected version before checkout

Select your preferred colour, lens option and size, then reread the product’s Size & Fit Details. Make sure you are comparing the version you intend to order.

If information is unclear, contact Ardor Eyewear with the model code, selected lens width and your current frame measurements. Ask which bridge and temple dimensions apply to that combination.

Read the returns policy before purchasing. It currently states a 14-day return period from receipt, with return postage paid by the customer. Non-prescription eyewear must include its original packaging, case and cloth; customised lenses and additional coatings have refund exclusions.

Frequently asked questions

Are men’s and women’s Ray-Ban sizes different?

Choose by measurements rather than the gender label. Several models discussed here are listed as unisex, so the same frame can suit different wearers when its dimensions and bridge fit are appropriate.

Is pupillary distance the same as sunglasses size?

No. PD measures the distance between your pupil centres and helps position prescription lenses. It does not replace frame measurements. For prescription orders, see Ardor Eyewear’s PD measurement guide.

Can I choose oversized sunglasses without sizing up?

Yes. Look for a design with greater lens coverage that still fits your nose and temples securely. A deliberately oversized appearance does not require loose arms or a slipping bridge.

Can virtual try-on confirm the right size?

Use it to judge appearance and proportions. It cannot tell you whether the bridge pinches or the arms press behind your ears, so combine it with measurements and a physical fitting where possible.
