Ray-Ban Size Guide

Ray-Ban is a premium eyewear brand renowned for its iconic sunglasses and prescription glasses. Unlike traditional clothing, Ray-Ban frames are sized by lens width measured in millimetres, which determines the overall fit and aesthetic of the style. Ray-Ban frames follow standard sizing conventions and cater to a wide range of face shapes and sizes, from small to extra-large. The brand's sizing is consistent across collections, though design elements such as lens tilt and frame shape may vary subtly between sizes, particularly in modern styles like the New Wayfarer.

Understanding Ray-Ban Frame Sizing

Ray-Ban frames are identified by three key measurements printed on the inside of the temple (arm). These measurements are expressed in millimetres as follows:

1. Lens Width: The first number (e.g. 52) represents the width of each lens in millimetres. This is the primary size indicator and determines how large or small the frame appears on your face.
2. Bridge Width: The second number (e.g. 18) is the distance between the two lenses, measured across the bridge of the nose.
3. Temple Length: The third number (e.g. 140) indicates the length of the arms (temples) in millimetres.

To find your Ray-Ban size, locate the three-number sequence on the inside left temple of the frame. For example: 52–18–140.

How to Find Your Correct Size

Method 1: Credit Card Test

A standard credit card is approximately the same width as a typical lens size (55mm). Use this simple method to estimate your size:

1. Hold a credit card horizontally with one edge positioned at the centre of your nose.
2. Observe where the opposite edge of the card aligns with your eye.
3. If the card edge extends beyond your eye, you need a small size (52mm or smaller).
4. If the card edge aligns at the end of your eye, you need a medium size (55mm or standard).
5. If the card edge does not reach the end of your eye, you need a large size (58mm or larger).

Method 2: Measuring Your Face

1. Using a ruler or measuring tape, measure the distance from the outer corner of one eye to the outer corner of the other eye. This is your total frame width.
2. Compare this measurement to the "Frame Width (mm)" column in the size chart above.
3. If your measurement falls between two sizes, choose the larger size for comfort.

Method 3: Check Existing Frames

1. Locate the size marking inside the left temple of any sunglasses you already own and wear comfortably.
2. Find the three numbers separated by hyphens (e.g. 54–18–140).
3. The first number is your lens width—use this as your Ray-Ban size.

Product-Specific Guidance

Sunglasses (All Styles)

Ray-Ban sunglasses are the core product category. Most faces fit the standard 55mm size comfortably. However, the New Wayfarer exhibits notable design changes across sizes: the 52mm offers a shorter, more tilted lens reminiscent of the Original Wayfarer, whilst the 58mm features a straighter, more modern profile. The Original Wayfarer is most popular in 50mm. Aviator frames run larger relative to their lens width, so a 55mm Aviator may feel similar in overall width to a 50mm Wayfarer.

Prescription Glasses

Ray-Ban prescription frames follow identical sizing to sunglasses. Bridge width becomes more important for comfort when wearing glasses daily, as the nose pads rest on the bridge. If you have a narrow nose bridge, select frames with a smaller second number (e.g. 16–18mm rather than 20–22mm). Temple length (third number) affects how the arms sit over your ears; if you have a smaller head or find frames slip, look for shorter temples (typically 135–138mm).

Junior / Children's Frames

Ray-Ban offers "RJ" prefixed models designed for children. These typically start at 47–50mm and do not follow the standard sizing categories above. Children's frame fit should be assessed in person, as proper positioning over growing faces is essential.

Sizing Tips

• Standard Size for Most: If you are unsure, start with a 55mm (Medium) size—this will fit approximately 9 out of 10 adult faces correctly.
• Design Changes with Size: In the New Wayfarer, larger sizes (58mm) have less lens tilt and a more contemporary appearance, whilst smaller sizes (52mm) retain more of the classic vintage tilt. Choose based on your preferred aesthetic as well as face fit.
• Bridge and Temple Matter Too: Lens width is the primary size indicator, but if frames feel too loose or too tight on your nose, or if the arms don't rest comfortably over your ears, check the second and third measurements. A different frame style may offer better proportions even at the same lens width.
• Check Product-Specific Charts: Ray-Ban sizing follows standard conventions, but individual models may have slight variations in overall fit. Always review the product description or size details when purchasing online, and read customer reviews for real-world fit feedback.
• Same Size, Different Fit: A 55mm Clubmaster will appear smaller and narrower than a 55mm Aviator because the Clubmaster has a smaller overall frame width despite the same lens measurement. Compare frames using the full three-number code, not just lens width.
• Contact Customer Service: If you remain uncertain after using the credit card test or measuring your face, Ray-Ban's customer service team is available to help. Email or contact the retailer before purchasing to avoid returns.
• Temple Length for Comfort: If you have a smaller head or find that most sunglasses slip, look for frames with shorter temples (135–138mm). Conversely, larger faces may need longer temples (142–145mm) to avoid pinching at the ears.
