Frame Style Guide: Finding Your Perfect Fit

Understanding Face Shapes

The first step to finding flattering frames is identifying your face shape. Most faces fall into one of five categories:

Round Face

Characteristics: Soft, curved features with similar width and length.

Best frames: Angular shapes that add definition

• Square or geometric frames
• Cat-eye and upswept styles
• Wide frames to elongate the face
• Frames wider than they are tall

Avoid: Round or oval frames that repeat your face shape

Oval Face

Characteristics: Balanced proportions, slightly longer than wide, curved jawline.

Best frames: Nearly any style works! You have the most flexibility

• Oversized frames
• Cat-eye styles
• Geometric shapes
• Tortoiseshell patterns

Avoid: Very large or heavy frames that overwhelm delicate features

Square Face

Characteristics: Angular jawline, equal width and length, prominent forehead and chin.

Best frames: Curved styles to soften sharp angles

• Round or oval frames
• Cat-eye (upward sweep)
• Clubmaster style
• Wayfarer style

Avoid: Heavy, angular frames that emphasize jawline

Heart Face

Characteristics: Wider forehead, narrow jawline, prominent cheekbones.

Best frames: Wider at bottom to balance forehead

• Bottom-heavy frames
• Rounded or oval styles
• Frames with wider lower rims
• Aviator style

Avoid: Frames top-heavy or very angular

Rectangle/Oblong Face

Characteristics: Noticeably longer than wide, narrow jawline, prominent chin.

Best frames: Wider frames to add width

• Oversized frames
• Wide, bold styles
• Cat-eye (wider bottom)
• Clubmaster style

Avoid: Small, delicate, or narrow frames

Frame Materials and Durability

Beyond style, the material affects comfort, durability, and appearance:

Acetate

• Most popular material for blue light glasses
• Lightweight and comfortable
• Available in endless colors and patterns
• Hypoallergenic (good for sensitive skin)
• Durable (3-5 year lifespan)
• Easy to repair

Metal

• Classic, professional appearance
• Very lightweight (especially titanium)
• Highly adjustable for perfect fit
• Can oxidize or corrode over time
• More expensive
• Best for those without metal sensitivity

Hybrid (Mixed Materials)

• Combines metal and acetate for best of both worlds
• Often more expensive
• Great for versatile style options

Frame Size Guide

Proper fit is essential for comfort and visual clarity:

Measuring Your Frames

Most eyeglasses have three measurements (usually marked inside the arm):

• Lens width: Width of one lens (typically 48-60mm)
• Bridge width: Distance between lenses (typically 14-24mm)
• Temple length: Length of the arm (typically 130-150mm)

Finding Your Size

• If you wear glasses, check your current pair for the measurements
• For online shopping, most retailers provide detailed size guides
• Measure from temple to temple across your face—this is your ideal total width
• Remember: wider frames suit longer faces; narrower frames suit rounder faces

Color and Pattern Selection

Your frame color should complement your skin tone and personal style:

Cool Skin Tones

• Best colors: Silver, black, cool pastels, jewel tones
• Tortoiseshell: Avoid warm-toned tortoiseshells
• Avoid: Warm gold, bronze, copper

Warm Skin Tones

• Best colors: Gold, warm wood tones, coral, warm pastels
• Tortoiseshell: Classic warm tortoiseshell works great
• Avoid: Cool silver, cool pastels

Neutral Skin Tones

• Best colors: You can wear anything!
• Go with your personal preference and style
• Consider your eye color and hair for extra harmony
