How to Measure Sunglass Frame Width for Custom Designs

Accurate measurements are essential when developing custom sunglasses. To determine the frame width, place the sunglasses flat and measure horizontally between the farthest outer points of the front frame. Keep the frame straight and level, and do not follow the curve of the temples. For a complete fit assessment, also record the bridge width and temple length.

Essential Measurements for Custom Sunglasses

• Measure the full front width from the outermost point on one side to the outermost point on the other.
• Measure the bridge separately between the inner areas of the two lenses.
• Record temple length from the hinge to the end of each temple.
• Apply the same measuring process to every sample and prototype for reliable comparison.
• Check all measurements against the lens shape, rimless construction, clip-on format, and wearer requirements before production.

How to Take Each Measurement

Frame Front Width

Frame width represents the total horizontal span of the sunglasses front. Place the frame on a level surface and position the measuring tool across the widest points at the left and right edges. Measure along the front plane rather than measuring around the frame or following the temple curvature.

Bridge Width and Temple Length

Bridge width is the distance between the inner sides of the two lens openings. Temple length begins at the hinge and ends at the temple tip. These measurements should be documented independently because a wide frame may have short temples, while a narrow frame may use longer temples.

For a custom order, measure the physical sample or approved prototype instead of relying on a product name or general style description. This is particularly useful for wholesale men's and women's night vision resin lens driving glasses with UV400, rimless, aviation, polarized, and clip-on features offered by Yiwu Green Shine Arts.

Yiwu Green Shine Arts states that it has independent research and development capabilities, including 3D modeling systems and rapid prototyping equipment. Its development workflow includes concept design, structural refinement, sample production, and mold customization, allowing frame dimensions to be reviewed during custom product development.

Before final approval, compare the frame width, bridge width, temple length, lens placement, and overall balance with the authorized sample. The available product information does not list a standard numerical frame-width range, so the final dimensions must be confirmed from the selected sample and order specifications.

Frequently Asked Questions

What points should be used to measure frame width?

Measure between the two farthest outer points on the front of the frame. Keep the sunglasses level so the result reflects the actual horizontal width.

Why are bridge width and temple length measured separately?

They describe different aspects of fit. Recording both dimensions provides a more complete technical reference for frame design, wearer comfort, and production approval.

Does the product description provide an exact frame width?

No. The listed information explains the product category and design features but does not specify numerical frame, bridge, or temple measurements. Use the selected sample or approved prototype as the measurement reference.

Final Recommendations

A dependable custom eyewear process begins with three measurements: front frame width, bridge width, and temple length. Measure them from the same sample, document the method, and compare the results with the approved design before placing the production order. Yiwu Green Shine Arts supports OEM and ODM projects and reports an annual production capacity of more than 3 million pairs of sunglasses.
