Best sunglasses for a big head: 7 tips & examples


What are the best sunglasses for big heads?


The best sunglasses for big heads provide a larger lens width, bridge width and temple length. These enlarged aspects give greater comfort, style and potentially even better sun protection.


With that in mind, this handy guide is to help you find the perfect sunglasses frame for you.

Check out the following 9 tips explaining what to look for in a large pair of sunglasses 

Let's delve in.

1. Frame size

Just like clothes or footwear, sunglasses follow a standard sizing system.

But how are sunglasses measured?

Most sunglasses show their dimensions on the interior of the frame, usually printed or etched on the temples (arms.) Always measured in mm, they’ll look like this;


63 □ 18 145


  • 63 = lens width
  • 18 = bridge width
  • 145 = temple length


The best sunglasses frames for a big head will tend to have a large lens width of 55mm or more and a temple length of 145mm or more.

2. Lens width

63 □ 18 145

The overall width of a lens is generally what dictates the size of a sunglasses frame.

Bigger sunglasses can have lens widths of 50 mm or more, depending on their frame shape. Round shape frames won’t be quite so wide compared to boxy ones, but this is merely a style thing.

To avoid that undersized goofy look, proper lens width ensures better aesthetics and sufficient lens coverage for your eyes.

Frames which are too narrow look silly and make your head seem even bigger. They also allow more ‘light leak’ from the sides, causing sunlight to bounce back into your eyes. Not fun.

To alleviate bounce back, you might consider investing in rear surface anti-glare lens coatings.

Conclusion: the best sunglasses for a big head have wider lenses which reach to the outer edges of your face, past your eyes to provide sufficient lens coverage from the sun.

3. Bridge width

63 □ 18 145

The second set of frame digits denote the bridge width of your sunglasses; the gap where your nose locates between the lenses.

Adult bridges vary between 16 to 24 mm depending on your gender, age and ethnicity. Sunglasses manufacturers like us tend to make adult frames with a bridge around 18 mm or so.

But there’s a twist.

You can have a wide nose, but still need a narrow bridge. And vice vera.

Because your sunglasses sit on the upper maxilla and nasal bones surrounding your nose, these features determine your ideal bridge size.

For the best results, compare your existing bridge size with any prospective new sunglasses. This way you’ll have a rough idea of what you’ll need.

A difference of a few mm isn’t a big deal, but avoid overly narrow or overly wide bridges so the frame rests properly on your face.

Conclusion: the best sunglasses for a wide bridge let the frame rest properly on your nose without pinching or sitting high on your face. Instead, the frame will rest securely without slipping down.

4. Temple length

63 □ 18 145

Temple length is always the last set of digits in the size series.

But watch out, some brands don’t label their frames with this dimension.

Becuase sunglasses are more of a ‘one size fits all’ sort of frame, manufacturers tend to use standard temple lengths of around 140 mm and just leave this out.

Adult temple lengths vary between 130 to 140, but anything beyond that length is considered as large-fit. With a big head, you’ll definitely need at least a 145 mm temple length or longer.

If you can find sunglasses with a 155 mm temple, these are at the larger end of the spectrum for temple lengths.

Temples which are too short end up ‘perching’ on top of your ears and pull the frame closer into your face. This often causes the frame to tilt forwards on your head which is uncomfortable and lets more sunlight in from above.

For the best results, compare your existing temple length with any prospective new sunglasses.

5. Face shape

What face shape do you have?

You'll probably fall into one of two categories; square or round.

Large square heads tend to suit soft sunglasses shapes such as the classic Aviator, Wayfarer or even those 50's round styles. With a wide jaw line and sharp facial features, ovalized frames with round corners create a nice balance to your face.

Large round heads suit more angular geometric shaped sunglasses. If you have gentle facial features and soft cheeks, aggressive lines and sharp corners will contrast your face and bring nice definition.

If you're somewhere in the middle, that's totally fine. Just make sure you find a frame that you're comfortable wearing in terms of fit and look.

The main thing to remember is contrast.

6. The narrowing effect

If you’re conscious of having a wide head, here’s a handy style hack.

To create a narrowing effect on your face, avoid sunglasses with thick chunky temples (arms) on the sides.

Sunglasses with thick ‘paddle’ sides tend to draw attention to the widest regions of your head. This gives the impression of width, which you’ll probably want to avoid.

Subsequently, the best sunglasses for a round/wide head should have a thin temple and a dominant frame-front. This handy trick creates greater contrast on your face rather than the sides.

Large sunglasses with a thin temple give the illusion of a smaller head.

If you have a long face or a receding hairline, tall sunglasses frames like Aviators are also great way to visually ‘shorten’ your face.

7. Material and colour

Depending on your dress-style, you’ve got a wide variety of colour choice when finding the best sunglasses for a big head.

Ultimately, this is a fashion decision so you’re best sticking to a colour of sunglasses frame that you’ll feel comfortable wearing out and about in the sun.

This might seem obvious, but the biggest aesthetic advantage of sunglasses is the large dark lenses. They give you much wider scope in terms of frame colour becuase the majority of the contrast is created by the lenses.

If you have a loud and vibrant style, this is your chance to experiment with outlandish colour combinations. Those big dark lenses will forgive the most outlandish sunglasses frames.


If colour isn’t your thing, a neutral sunglasses frame is probably the safest bet when it comes to harmonising with your wardrobe.

8. Quality

Which red-blooded male actually likes shopping?

Invest wisely and high-quality sunglasses should last you summer after summer.

Long term, this is going to save you from yet another seasonal search for sunglasses that’ll actually fit you. This approach is infinitely better for the environment and for your wallet too.

Plus, cheap sunglasses tend to break easily or even lack proper UV light protection.

Luckily for you, our British made sunglasses are handmade from premium grade cellulose acetate and bespoke metal hardware.

Alternatively, you might prefer a slim pair of large Aviators from our handmade Japanese sunglasses collection.

9. Polarised lenses

When it comes to quality, lens choice is a crucial factor.

So, what’s the difference between polarised and non polarised sunglasses?

Non polarised lenses provide 100% UV protection. This is the most crucial aspect of your sunglasses.

But polarised sunglasses take your sunglasses to a whole new level.

They still protect your eyes from UV light, but they use an inbuilt filter sandwiched inside the construction of the lenses.

This filter is called a polariser and blocks reflected glare from flat shiny surfaces such as nearby water, cars, roads or buildings. For you, this means consistent, silky smooth vision in all kinds of sunlight.

Simply put, polarised lenses are a superior kind of sun lens which you can learn more about here, if you fancy diving deeper.

10. Some bonus tips


Are there sunglasses for big heads?

Sunglasses with a lens width of 64 mm or more are suited towards big heads. They do exist, but are much less common than medium or small sunglasses frames.

For reference, refer to the chart below.


What is the biggest size for sunglasses?

Adult sunglasses range from small to to extra large with lens widths varying between 45 mm to more than 60 mm. As a general guide, here is a size chart.

16 mm – 20 mm

140 mm – 150 mm

What glasses suit a big head?

Large rectangular shaped frames suit a big head. Due to their dominance on your face, they make your head appear smaller by visual contrast. Steer clear of undersized frames as they’ll usually emphasise your head size.


Do aviators look good on men?

Square shaped aviators look good on men with soft facial features. Their sharp angular lines bring balance to faces with less definition. Conversely, round aviators look good on men with strong jawlines and prominent cheekbones.


How do I know if my glasses are too big?

If your glasses are too big, the frame slips down your nose or the temples will protrude from behind your ears. Glasses that fit properly stay in position with the correct bridge width and temple length.
