A brief Guide To Perfect Frame Size

Here’s a Guide that’ll give you the quickest & easiest route to your best-fitting frames.

At Naina Opticals, most of our collections fall under the Medium and Small Size Category. This is because our frames are designed keeping in mind an ideal Indian face. In case you’re not sure of your frame size, you can always try buying a medium frame that fits most of the people. However, if you want to be 100% sure, follow any of the ways below to get to that perfect fit. While we’ve helped millions of happy customers with their perfect frame, yet, in a rare case, if you face any size issues, you can avail our 14-Day No Questions Asked Returns Policy. Although our lenses are custom-made according to your frame & power, yet, if you’re not happy, we’re not happy. So, we will refund your entire lens+ frame cost.
1. Using Size Of Your Current Frames

If you own a well-fitted pair already, try and peek at the insides of the temples to find out the measurements. It would look like a set of numbers which denote lens width, bridge width & temple length respectively. e.g. 52-15-165

2. Using A Ruler

In case your frames are older than a year, you might find the numbers faded. This gives doubt a chance and you may end up buying a wrong size.

So let’s have a look at the next simplest way. For this, you will need:

  • A Millimeter Ruler / Cloth Measuring Tape
  • Pen/Pencil to Record the Readings

Take cues from the ranges below to avoid any mistakes.

Lens Width/Diameter – The horizontal width of each lens in millimeters. It ranges between 40-62mm.

Bridge Width – The distance between the two lenses in millimeters. It ranges between 14-24mm.

Temple Length – The length from screw to temple tips. It ranges between 110-150mm.

3. Using A Clothing Size Guide

You’d wonder how a clothing guide can help you. But broadly, your regular T-shirt can help you solve this mystery like a pro. Here’s how –

  • People who wear Small (S) size:

It is likely your face structure would be small too. In general, frames with less than or equal to 50mm of lens-width would fit you easily in case of eyeglasses. For sunglasses the width of 55mm or less should be your choice.

  • People who wear Large (L) size:

Your spectacles must be 55mm wide or more. In case of shades, this will be 65mm or more.

  • People who wear Medium (M) size:

You can go for frames between 51mm to 54mm of lens-width for eyeglasses and 56mm to 64mm for sunglasses.

4. Using Debit/Credit Card

Did you know you could find out your frame size with your debit/credit cards too?

Interestingly, the standard width of the card can be compared to a medium (M) sized frame. Let’s see how.

Place one edge of the card at the center of your nose & if:

  • The other end of the card ends at the tip of your eye; a medium sized frame would fit you right
  • The card width extends the tip of the eye; a small frame is what you need
  • If the edge of the card ends before your eye’s tip, you’ll need a (L) large-sized frame.
