Use simple labeled arrows for buttons. Use the exact arrow required by the math or logic rule in an equation.
Technical note: Use familiar single arrows with clear labels for navigation. In mathematics and logic, choose the exact arrow defined by the notation, because double arrows and harpoons can have formal meanings.Reviewed by CoolSymbol.now Editorial · August 2, 2026What you need to know
A left or right arrow can support Back, Next or a movement control, but direction alone may be ambiguous.
Single, double, long and harpoon arrows can represent mappings, implication, equivalence, limits or chemical relations.
Do not choose a formal double arrow solely to decorate a Next button.

01
Navigation needs a clear action
Use a simple single-shaft arrow for navigation. It reads as movement or direction, which is what a button needs.
Keep double-shaft arrows for maths and logic. There they mean implication, which is a specific claim.
02
Mathematical arrows are operators
Triangles without shafts belong to playback and expand controls. Readers already know that convention.
- → often shows direction or mapping
- ⇒ often shows implication
- ⇔ often shows equivalence
- Harpoons can have specialist uses
03
Keep the two contexts separate
Matching the shape to the job removes a small friction every time someone reads it.
- Label interface controls
- Follow the notation reference
- Test the final font
04
The convention behind each shape
An arrow is also relative to reading direction. Next points right in English and left in Arabic. Interface frameworks flip icons automatically. A literal arrow typed into a sentence does not.
