Round, Oval, or Square: How to Choose a Seal Shape

Most seal and stamp designs fall into a handful of shapes, and the shape you pick says almost as much as the text inside it. Here's a quick rundown.

Round seals

The most common shape for company chops, notary stamps, and official seals. The circular border gives even visual weight to text running around the edge, which is why it's the default for "name + organization" layouts.

Oval seals

Common for personal and decorative stamps. The elongated shape works well for a single line of text or a name combined with a small emblem in the center.

Square and rectangular seals

Typically used for date stamps, "received" / "approved" stamps, and signature blocks where the content is a short phrase rather than a circular ring of text.

Choosing a shape

• Matching convention — if you're recreating a specific regional or institutional style, the shape is usually fixed by convention rather than preference.
• Text length — long text reads better around a circle or oval; short text reads better in a straight line inside a square.
• Where it'll be used — stamps meant to overlap a signature or date field are usually rectangular for spacing reasons.
