How many sides does a 3d plus sign have?

Answer 1

A 3D plus sign typically has 18 sides.

Here’s how it breaks down:

A standard plus sign has 6 arms (top, bottom, left, right, front, and back).

Each of those arms contributes multiple flat surfaces: front, back, left, right, top, and bottom faces.

When the plus sign is extruded into 3D, each intersection creates additional visible faces.

So, while it may look simple, a 3D plus sign is made of multiple rectangular and square faces. A clean design usually has 18 separate flat surfaces (sides) if constructed symmetrically.

If you’re looking into 3D sign letters in Boca Raton or trying to create a clean dimensional letter signage for your business, this structure matters—especially when choosing materials and finishes. At SpeedPro Boca Raton, we often guide clients through these design details when building custom dimensional letters or a dimensional sign in Boca Raton. The number of sides affects not only design but also how light and shadow play off the sign in real environments.

Hope that helps!
