Right Arrow (Double) in LaTeX (\Rightarrow)

Where it is used

Draws a short double-shafted right arrow, the standard implication sign between formulas.

\Rightarrow states that one formula implies another, as in p \Rightarrow q, and labels the forward direction (\Rightarrow) in proofs of equivalence. \implies prints the longer \Longrightarrow with extra thick spacing and suits implications between complete statements. Probability writes weak convergence of distributions as X_n \Rightarrow X, and term rewriting uses it for a reduction step. Boolean algebra uses it for the conditional. Prefer it over the single arrow \to when the objects are statements rather than sets or functions.

Frequently asked questions

How do I write Right Arrow (Double) in LaTeX?

Type \Rightarrow in math mode, for example $x > 2 \Rightarrow x^2 > 4$. It works in plain LaTeX without loading any package.

Which package do I need for \Rightarrow?

None. \Rightarrow is part of standard LaTeX, so it compiles with nothing in the preamble but the document class.

Can I use \Rightarrow in text mode, or only in math mode?

Only in math mode. Outside $...$ LaTeX stops with "Missing $ inserted", so write $\Rightarrow$ in running text. If you only need the glyph in text, paste the Unicode character ⇒ instead (with XeLaTeX or LuaLaTeX and a font that has it).
