Increment Symbol
∆ is a Greek delta symbol commonly used to indicate change or an increment in math and writing.
U+2206
The symbol ∆ (U+2206) is read as “delta” and is widely used to mean change or an increment. It appears in formulas, notation, and even everyday writing to signal “difference from” or “the next step.” Below you’ll find practical ways to copy, type, and use it in documents and code.
Increment Symbol Meaning
∆ is the Unicode character named “INCREMENT” with code point U+2206. It is visually a bold form of Greek delta and is commonly used to represent a change or difference (for example, Δx) in mathematics, science, and technical writing. In many contexts, it can also suggest an increment—i.e., “add this amount” or “the step up from a baseline.” Because it’s a dedicated Unicode symbol, it’s preferable to approximations like a plain “delta” word when you need consistent typography across fonts and platforms.
Common uses
- •Write math and science notation for change, such as Δx or Δt.
- •Indicate an increment in instructions or specs (e.g., “increase by ∆step”).
- •Label differences in reports (e.g., “∆ in revenue vs. last quarter”).
- •Annotate charts and data summaries with “∆” to show variation.
- •Use in UI text for “delta”/“change” indicators in dashboards.
