How to Choose Glasses for Your Face Shape: Expert Guide
Choosing the right glasses frame isn't just about prescription strength or style preferences—your face shape determines which frames will enhance your natural features and which ones will overwhelm them. Understanding the geometry of your face and how different frame styles interact with it can transform your entire look.

Identifying Your Face Shape
Before diving into frame recommendations, you need to accurately determine your face shape. Stand in front of a mirror and pull your hair back completely. Using a washable marker or lipstick, trace the outline of your face directly onto the mirror. Step back and examine the shape you've drawn.
Oval faces are longer than they are wide, with gently rounded edges and a slightly narrower jawline than forehead. Round faces have similar width and length measurements with soft, curved lines and fuller cheeks. Square faces feature a strong jawline with roughly equal face width and length, plus a broad forehead. Heart-shaped faces have a wider forehead and cheekbones that narrow to a pointed chin. Diamond faces are widest at the cheekbones with a narrow forehead and jawline. Rectangular faces are longer than they are wide with a strong, angular jawline.
Frame Styles for Each Face Shape
Oval Faces: The Universal Canvas
Oval faces are considered the ideal shape because they can wear almost any frame style successfully. The key is maintaining the natural balance rather than disrupting it. Avoid frames that are too large or too small for your face size.
Best choices: Rectangular frames, square frames, cat-eye styles, and round frames all work beautifully. The Navigator Brown acetate frame exemplifies the perfect rectangular option for oval faces, offering structure without overwhelming your natural proportions.
Round Faces: Adding Definition
Round faces benefit from frames that add angles and create the illusion of length. The goal is to make the face appear longer and thinner while adding definition to soft features.
Best choices: Rectangular frames, square frames, and cat-eye styles work exceptionally well. Choose frames that are wider than the broadest part of your face. Avoid circular frames, which will emphasise roundness. Angular acetate frames like the Vintage collection provide the sharp lines that complement round faces perfectly.
Square Faces: Softening Strong Lines
Square faces have strong, angular features that benefit from softer frame shapes. The objective is to balance the angular jawline and add curves to create visual harmony.
Best choices: Round frames, oval frames, and cat-eye styles with curved edges. Frames should be wider than your jawline to create balance. Rimless styles also work well by minimising additional structure. The SkyAura round frames offer the perfect contrast to angular features while maintaining sophisticated appeal.
Heart-Shaped Faces: Balancing Proportions
Heart-shaped faces need frames that draw attention downward and add width to the lower portion of the face while minimising the broader forehead area.
Best choices: Bottom-heavy frames, cat-eye styles with upswept corners, and round frames work well. Avoid top-heavy frames or those with decorative elements on the upper rim. Semi-rimless styles where the bottom portion has more visual weight are particularly flattering.
Diamond Faces: Highlighting Cheekbones
Diamond faces have beautiful cheekbones that should be complemented rather than hidden. Choose frames that enhance this natural asset while adding width to the forehead and chin areas.
Best choices: Cat-eye frames, oval frames, and rimless styles. Frames with detailing on the brow line help balance the narrow forehead. The Ameth collection features elegant detailing that works particularly well for diamond face shapes.
Professional Fitting Considerations
Beyond face shape, several technical factors determine proper frame fit. The frame width should align with your face width—glasses shouldn't extend beyond your temples or pinch at the sides. Your eyes should sit in the centre of each lens, both horizontally and vertically.
Bridge fit is crucial but often overlooked. A properly fitted bridge distributes weight evenly and prevents sliding. For narrow bridges, choose frames with adjustable nose pads. Wider bridges work better with integrated plastic nose rests.
Temple length affects both comfort and appearance. Standard temple lengths range from 135mm to 150mm. Temples should rest gently behind your ears without pressure points. In cities like Brighton and Liverpool, many opticians report that customers often choose frames based purely on style, ignoring these critical fit factors that determine long-term comfort.
Common Frame Selection Mistakes
One counterintuitive mistake many people make is choosing frames that match their face shape rather than complement it. Round faces don't need round frames—they need contrast. This principle applies universally across all face shapes.
Another frequent error involves ignoring lifestyle factors. Active individuals in Birmingham or Edinburgh who choose delicate metal frames often find them inadequate for their daily activities. Consider flexible memory metal frames or impact-resistant materials if you lead an active lifestyle.
Size miscalculation represents the most common technical error. Many people select frames that are either too large (thinking they look fashionable) or too small (believing they're more flattering). The correct frame size should be proportional to your face size, regardless of current trends.

Frequently Asked Questions
Can I wear any frame style if I really love it, regardless of my face shape?
While face shape guidelines provide the most flattering options, personal preference matters significantly. If you love a particular style, ensure the fit is correct and the proportions aren't dramatically mismatched. Sometimes confidence in wearing a style you love outweighs strict adherence to shape rules.
Do prescription strength limitations affect frame choices?
Yes, strong prescriptions require careful frame selection. High prescriptions work better with smaller frame sizes to minimise lens thickness and weight. Avoid rimless styles with very strong prescriptions, as the lens edges become more noticeable. Choose frames with adequate lens depth to accommodate progressive lenses if needed.
How often should I update my frame style?
Frame durability typically lasts 2-3 years with regular use, but style preferences may change more frequently. Consider having a primary pair for daily wear and a secondary pair for different occasions or style moods. This approach allows experimentation without committing to a single look.
Are there specific frame materials better suited to certain face shapes?
Material choice depends more on lifestyle and skin sensitivity than face shape. However, metal frames tend to appear more delicate and work well for adding subtle structure, while acetate frames make bolder statements and provide more dramatic contrast to facial features.
