# Referencing Figures in LaTeX

Small tip:

Whenever referencing figures in LaTeX, do not refer in the following way:

Blah blah \ref{figure1}.

^ Would give the following output:

Blah blah ??.

However,

Blah blah \ref{figure1} .

^ will give the following output:

Blah blah [1] .

The difference is the small space between the closing curly braces of “figure” and “period”.
