Do oval diamonds look bigger than rounds?

Usually yes, at the same carat, because the outline is stretched. The width can still be narrower than the round’s diameter.

Oval diamond size chart

Ovals are sized by length and width, not by a single diameter.

Length, width, and common ratios

A 1 carat oval is often about 7.5–8.0 mm long and about 5.3–5.7 mm wide. A 2 carat oval is often about 10–10.5 mm long and about 7 mm wide. Ratios near 1.35–1.50 are a common preference; longer ratios look more elongated.
