For a round face, the goal is usually to add structure and balance out the natural softness and curves. The size of the glasses frame isn’t just about numbers—it’s about proportions and style. Here’s a detailed guide:

1. Frame Width

• Rule of thumb: The frame should be wider than the widest part of your face.
• This visually elongates the face and makes it appear slimmer.
• Avoid narrow frames—they emphasize roundness.

2. Lens Shape

• Best shapes: Rectangular, square, or geometric frames.
• Avoid round or overly circular frames—they make the face look rounder.

3. Frame Size Numbers

Glasses frames usually have three numbers: eye size – bridge size – temple length (e.g., 52-18-140 mm).

For a round face:

1. Eye size (lens width): Medium to large (50–58 mm). Bigger lenses help balance round cheeks.
2. Bridge width: Medium (16–20 mm). Ensure the frame sits comfortably on the nose without pinching.
3. Temple length: Standard (135–145 mm). Longer temples help the frame sit properly without looking tight.

4. Frame Style Tips

• Frames with angular lines give structure.
• Darker colors or patterns near the eyes draw attention upward.
• Frames with a slight upsweep (like cat-eye) can also create a slimming effect.

Summary: For a round face, choose a medium-to-large rectangular or angular frame, slightly wider than your face, with medium bridge and temple size. Avoid small, round, or delicate frames.
