What Reading Glasses Sizes Mean

Reading glasses sizes involve more than just a simple number – they represent a precise measurement system that determines how well your eyewear will fit and function. Understanding these sizes is crucial for selecting glasses that provide optimal visual comfort and clarity.

Typically, reading glasses sizes comprise two primary measurements: lens width and bridge width. The lens width represents the horizontal diameter of each lens, usually ranging between 40mm to 62mm. This measurement determines how much of your visual field will be covered and how proportional the glasses will look on your face. The bridge width, measuring the distance between lens frames, ensures the glasses sit comfortably across your nose without slipping or creating pressure points.

To help you find the perfect fit, most reading glasses follow a standardised sizing chart that breaks down measurements into small (48-50mm), medium (52-54mm), and large (56-58mm) categories.

reading glasses measurements These categories help match frame dimensions to different facial structures. Understanding the Reading Glasses Fit Guide for Better Vision can provide additional insights into selecting the right size for your specific needs.

When shopping for reading glasses, pay attention to how the frames sit on your face. A well-fitted pair should rest comfortably without sliding down your nose or creating pressure behind your ears. Consider trying different sizes and styles to find the most comfortable and aesthetically pleasing option that complements your facial features and personal style.

Key Frame Measurements and Their Impact

Understanding frame measurements goes far beyond simple numbers – these precise dimensions directly influence your reading glasses’ comfort, functionality, and overall visual experience. Each measurement plays a critical role in determining how well your glasses will perform and feel throughout daily use.

Here’s a concise summary of key reading glasses frame measurements and their impact:

Measurement Typical Range Role in Fit & Comfort
Temple Length 130mm - 145mm Ear comfort
Glasses stability
Lens Width 40mm - 62mm Visual field
Frame proportion
Bridge Width 14mm - 24mm Weight distribution
Nose comfort

The primary frame measurements include temple length, lens width, and bridge width, each contributing uniquely to your glasses’ fit and performance. Temple length, typically ranging from 130mm to 145mm, determines how securely the glasses sit on your ears and prevent slipping.

Lens width impacts your visual field and aesthetic proportions, while bridge width ensures proper weight distribution and nose comfort. Understanding the Types of Reading Glasses for Better Vision can provide deeper insights into these nuanced measurements.

To help you navigate frame measurements effectively, consider these key considerations:

  • Temple Length: Determines ear comfort and glasses stability
  • Lens Width: Controls visual coverage and frame proportions
  • Bridge Width: Manages weight distribution and nose comfort
  • Frame Material: Influences overall weight and flexibility

When selecting reading glasses, remember that individual facial structures vary significantly. What works perfectly for one person might feel uncomfortable for another. Experimenting with different frame measurements and styles will help you find the ideal combination that provides both visual clarity and wearing comfort. Pay attention to how the glasses feel, not just how they look, to ensure you’re making the most informed choice for your unique needs.

How to Choose the Right Glasses Fit

Choosing the right glasses fit is an art form that balances comfort, functionality, and personal style. Your reading glasses should feel like a natural extension of yourself, providing clear vision without causing discomfort or constant adjustment.

Start by understanding your facial structure and measuring key dimensions. Face width, nose bridge height, and ear placement are critical factors in finding glasses that sit perfectly. Some faces work best with wider frames, while others look more balanced with narrower designs. Understanding Reading Glasses Frame Styles for Your Needs can help you navigate these nuanced selection criteria.

Consider these essential fit-checking techniques:

  • Ensure the frames sit level and don’t slide down your nose
  • Check that temple arms extend straight back without pressing or bending
  • Verify the lens width covers your entire reading zone without excess overhang
  • Test comfort by wearing the glasses for 10-15 minutes to assess potential pressure points

Remember that sizing isn’t just about measurements – it’s about finding glasses that make you feel confident and comfortable. Different frame styles suit different face shapes, so don’t hesitate to try multiple options. Your perfect reading glasses should feel so natural that you forget you’re wearing them, providing clear vision without constant readjustment or discomfort.

Comparing Frame Styles and Face Shapes

Matching reading glasses to your unique facial structure is more than a fashion choice – it’s about finding a harmonious blend of comfort, functionality, and personal expression. Understanding how different frame styles complement various face shapes can transform your eyewear from a mere visual aid to a stylish accessory that enhances your natural features.

Face shapes typically fall into five primary categories: round, oval, square, heart-shaped, and diamond. Each shape has distinctive characteristics that pair best with specific frame styles. Round faces benefit from angular frames that add definition, while square faces look best with softer, rounded frames that soften strong jawlines. Oval faces are considered the most versatile, able to pull off almost any frame style with ease. Guide to Glasses Frame Styles offers additional insights into navigating these nuanced style selections.

Consider these frame style recommendations based on face shape:

  • Round Faces: Choose rectangular or square frames to create visual angles
  • Square Faces: Opt for round or oval frames to soften strong facial lines
  • Oval Faces: Experiment with diverse frame shapes and sizes
  • Heart-Shaped Faces: Select frames wider at the top to balance facial proportions
  • Diamond Faces: Choose frames that highlight cheekbones and soften angular features

Remember that while these guidelines provide excellent starting points, personal comfort and individual style should always be your ultimate deciding factors. The most important aspect of selecting reading glasses is finding a pair that makes you feel confident and allows you to see clearly and comfortably.

Common Sizing Mistakes to Avoid

Choosing the wrong size reading glasses can transform what should be a simple vision solution into a frustrating experience. Many people unknowingly make critical sizing errors that compromise both comfort and visual effectiveness, turning what should be a helpful accessory into a source of constant irritation.

Oversized frames and undersized frames are two of the most common sizing pitfalls that can dramatically impact your reading glasses’ performance. Oversized frames tend to slip constantly, creating visual distraction and potential neck strain from repeated repositioning. Conversely, frames that are too small create uncomfortable pressure points, pinch your nose, and restrict your natural visual field. 7 Best Reading Glasses for Ladies and How to Choose offers additional insights into navigating these sizing challenges.

Avoid these critical sizing mistakes:

  • Ignoring temple arm length when selecting frames
  • Choosing frames based solely on aesthetic appeal
  • Neglecting to measure your current pupillary distance
  • Assuming one-size-fits-all reading glasses work for everyone
  • Purchasing glasses without trying them on or testing comfort

Remember that proper sizing is a holistic process involving multiple measurements and personal comfort assessments. What works perfectly for one person might be uncomfortable for another. Take time to try multiple sizes, move around while wearing the glasses, and pay attention to how they feel during different activities. Your reading glasses should feel like a natural extension of yourself – comfortable, functional, and almost unnoticeable during use.

No more headaches. No more squinting,

Reading glasses help stop headaches by reducing eye strain. When your eyes work too hard to focus on close-up tasks, it can cause tension around your eyes and forehead.

The right pair of glasses makes reading, phone use or computer work easier, easing eye fatigue and preventing headaches. They also improve posture, reducing neck and shoulder strain.

No more squinting at your phone, menus, food labels or books.

Our reading glasses are designed to bring clarity back to your everyday.

Read, work and relax without the strain. Say goodbye to squinting and hello to effortless vision in frames you’ll love to wear.

High-Quality Lenses

Our high-quality lenses are scratch-resistant and feature anti-glare protection for clear, comfortable vision.

Choosing your perfect pair

It's important you get the right fit for your glasses. Style. Fit. Function. We’ll show you the way.

Not sure what style to choose, or which frames will fit you best? Start with what you already love. Grab a pair of sunnies or glasses that fit you well - that’s your best reference point for shape and size.

Key Measurements

Every pair of our reading glasses comes with three key measurements to help you find the right fit, LW-BW-TL:

LW Lens Width The horizontal width of each lens (excluding the frame), measured at its widest point.
BW Bridge Width The distance between the lenses (across your nose).
TL Temple Length The length of the arms, from hinge to tip (including the bit that curves behind your ear)

Quick Tips

👀  Check the inside of the arm on your current glasses - most will have three numbers printed on the arm (eg 50-20-140, ie LW-BW-TL). These are your frame's measurements.
👀 Sunnies don’t usually include these, so you might need to break out the tape measure for those old-school stats.
📏 Use these numbers to match up with the fit guide on each of our product pages - and you’ll be looking sharp in no time.

 

Finding your lens power

It's important that you get the right lens power for your reading glasses. We’ll help you find your perfect pair.

Lens power (also called magnification strength) tells you how much help the lenses give your eyes to see things up close. It’s measured in dioptres (D) and for reading glasses comes in + (positive) numbers.

How It Works: 

+1.00 to +1.50  Great if you’re just starting to need a little help with small print.
+2.00 to +2.50 Ideal for more noticeable reading struggles or longer reading sessions.
+3.00 Best for strong magnification needs or serious close-up clarity.


If you're just starting out (you're getting headaches, you're squinting to see, you're holding text at arm's length to read it), try starting with a +0.5 or +1.00 or and adjust based on comfort.

💡 Pro tips

💡You can test different powers with printable reading diopter charts online - or try a few at a local retailer and see what feels best.

💡 You might be able to determine which strength of reading glasses you need by consulting a "lens power by age table" like this:

Age 40-44
Age 45-49
Age 50-54
Age 55-59
Age 61-65

Recommended power +0.5 to +1.0
Recommended power +1.0 to +1.5
Recommended power +1.5 to +2.0
Recommended power +2.0 to +2.5 
Recommended power +2.0 to +3.0 

 

💡If you’ve narrowed it down to two pairs of readers, it’s usually best to choose the one with less magnification.

💡 Non-prescription glasses are designed to work for reading or looking at other things up close, and if you are using them to see far away you should visit your local optometrist to discuss this.

💡 Note that a stronger lens is not always better, so reconsider a lens power that allows you to read something at a comfortable distance.

💡 You might find that you require different lenses for various tasks. If so, have a think about buying several pairs of reading glasses, each with a different strength of lens.

💡 If you're wearing reading glasses to see objects that are very close or very small, you will need stronger strength lenses with higher magnification than what the age-based reading glasses power chart might recommend.

💡 If you’re using reading glasses mainly while on the computer, perhaps choose a lower reading glass power. A lower reading glass power should be used when the viewing distance is longer. A lower strength of our reading glasses work great for computer readers. Keep a pair next to your screen.
