How to Measure Your Face for Sunglasses Fit: The Complete Guide for Online Shopping

Shopping for sunglasses online offers endless style options, but it comes with one big challenge: getting the right fit. Unlike trying on frames in a store, you can't rely on a mirror or feel. That's where knowing how to measure your face for sunglasses becomes essential. With a few simple measurements, you can confidently select frames that sit comfortably, stay secure during activity, and flatter your face shape.

At goodr, we design sunglasses for every adventure—from running and cycling to beach days and festivals. Whether you're eyeing the retro vibe of Dr. Ray, Sting or the sporty feel of Bucky™ Vision, understanding your face measurements ensures you pick a pair that stays put and looks great. This guide will walk you through the exact steps to measure frame width, temple length, bridge size, and lens height—so you never second-guess your online sunglass purchase again.

Why Measuring Your Face for Sunglasses Matters

When you buy sunglasses in person, you can quickly tell if a frame pinches your temples or slides down your nose. Online, you lose that physical feedback. Measuring your face bridges the gap, giving you reliable data to compare against the frame dimensions listed on product pages. A well-fitted pair of sunglasses won't cause headaches, leave marks on your nose, or fly off during a run.

For active lifestyles, fit is even more critical. Glasses that are too loose can bounce during a trail run, while frames that are too tight may fog up or feel uncomfortable after an hour. By taking a few minutes to measure, you can narrow down your choices to frames that match your unique proportions. goodr sunglasses come in a variety of shapes—square, round, shield, aviator—so there's a style for every face.

• Avoid returns and exchanges by measuring before you buy.
• Ensure your sunglasses stay secure during sports and outdoor activities.
• Match your face shape with the most flattering frame style.

Tools You Need to Measure Your Face

You don't need any special equipment. A flexible measuring tape (the kind tailors use) is ideal, but a ruler and piece of string will work just as well. You'll also need a mirror to check your positioning, a pen and paper to record numbers, and—optionally—a pair of sunglasses that already fit well for reference. If you're using string, mark the measurement points and then lay the string flat against a ruler.

Stand in front of a mirror in good lighting. Keep your face relaxed and look straight ahead. It's best to have a friend help for the most accurate readings, but you can do it alone by holding the tape steady with one hand and reading with the other. Measure twice to ensure consistency before writing down your final numbers.

• Flexible measuring tape or ruler with string.
• Mirror and good lighting.
• Pen and paper for recording measurements.

Step 1: Measure Your Face Width

Face width is the most important measurement for sunglass fit. It determines if the frame will align with your temples or be too wide or narrow. Using your measuring tape, measure the distance from temple to temple—the bony area just outside your eyes, not the middle of your ear. Start at one temple, pass the tape across the bridge of your nose, and end at the other temple.

Most adult face widths fall between 120 mm and 150 mm. This measurement corresponds to the total frame width listed in sunglass specifications. For example, goodr square frames like Always the Main Event typically have a frame width around 135–140 mm, suiting average to slightly wider faces. If your measurement is above 145 mm, look for oversized or XL frames. If below 125 mm, narrower frames will provide a better fit.

• Use the temple-to-temple distance across your nose bridge.
• Record in millimeters for easy comparison with product specs.
• Compare your measurement to the 'frame width' in product details.

Step 2: Measure Temple Length

Temple length refers to the arms of the sunglasses that rest on your ears. Standard temple lengths are 135 mm, 140 mm, or 145 mm. To measure your ideal temple length, take a reading from the hinge point at the front of your temple (where a sunglass arm would attach) to the point behind your ear where the arm would curve down.

Place the measuring tape at the front corner of your eye (near your temple hinge location) and run it along the side of your head to the top of your ear. Then extend it just below your ear's attachment point. This gives you the minimum temple length. For comfort, add 5–10 mm to allow the arm to curve naturally around your ear. If you wear hats or headphones, a shorter temple (around 135 mm) may interfere less.

• Most common temple lengths are 135 mm, 140 mm, and 145 mm.
• Measure from the hinge point at your temple to behind your ear.
• Add a small allowance for curvature around the ear.

Step 3: Measure Bridge Size

The bridge is the part of the frame that sits on your nose. A proper bridge fit prevents slipping and pinch marks. Measure the distance between your pupils, known as pupillary distance (PD), which closely relates to the bridge width. However, for sunglass shopping, you can directly measure the bridge of your nose: place the tape horizontally across the top of your nose, just above the nasal flare, where the frame would rest.

A typical bridge width ranges from 14 mm to 24 mm. Most goodr sunglasses feature a bridge of 16–19 mm, which accommodates a wide variety of nose shapes. If you have a low nose bridge, look for frames with adjustable nose pads or a keyhole bridge design. Remember that your bridge measurement combined with the lens width determines how well the glasses center on your face.

• Measure the horizontal distance where the frame rests on your nose.
• Compare with the 'bridge width' listed on product pages.
• Low nose bridges may need adjustable pads or specific frame styles.

Step 4: Measure Lens Width and Height

Lens width and height affect both coverage and style. For sun protection, you want lenses that cover your eye area without extending past your temples. Measure lens width horizontally across the widest part of one lens (if you have a reference pair) or use your face width measurement to estimate a suitable lens width. A common range is 50–60 mm per lens.

Lens height is measured vertically from the top to bottom of the lens. Taller lenses offer more coverage and a bolder look, while shorter lenses are sleek and sporty. For example, the round frames of Phoenix At A Bloody Mary Bar have a moderate lens height that suits both casual wear and low-light conditions. When shopping, check both width and height to ensure the lenses don't overwhelm your face or leave gaps at the sides.

• Lens width typically 50–60 mm; lens height varies by style.
• Match lens dimensions to your face width for proportional fit.
• Taller lenses offer more coverage for sunny conditions.

How to Use Your Measurements with goodr Sunglasses

Once you have your face width, temple length, bridge size, and desired lens dimensions, it's time to browse. goodr product pages include detailed frame measurements for each model. Compare your numbers against these specs. For instance, if your face width is 135 mm, a frame with a total width of 140 mm will provide a snug but comfortable fit. If your temple length needs are 140 mm, check that the arms on the model match or exceed that.

goodr offers a wide range of styles. Square frames like Five Stripes work well for round or oval faces, while round frames like Phoenix At A Bloody Mary Bar complement angular faces. Aviator styles such as Dr. Ray, Sting are versatile and suit many shapes. Use your measurements as a guide, but also consider the frame material—lightweight TR90 nylon flexes slightly for a forgiving fit, while acetate frames are more rigid and require precise sizing.

• Compare your face width to the 'Frame Width' on product listings.
• Match temple length to the 'Temple Length' spec.
• Consider face shape in addition to measurements for best style.

Common Mistakes to Avoid When Measuring

One common mistake is measuring face width from ear to ear instead of temple to temple. This results in an overly large measurement and frames that are too wide. Another error is measuring with a tense or smiling face; always relax your muscles. If you use a ruler without a mirror, you might tilt your head, skewing the numbers. Finally, don't forget to double-check your measurements—half a centimeter can make a big difference in fit.

Another pitfall is focusing only on frame width while ignoring temple length. Even if the frame fits your face, temples that are too short can cause the glasses to slide, while too-long temples may dig behind your ears. Also, ensure your bridge measurement accounts for the nose shape; a narrow bridge on a wide face may still need a wider bridge if the nose is flat. Take your time and measure in good light for accuracy.

• Don't measure ear to ear; use temple to temple.
• Relax your face and stand straight.
• Verify all three key measurements: width, temple, bridge.
