To find \( f(4) \) for the function \( f(x) = \left(\frac{x}{8}\right)^2 \), we substitute \( x = 4 \) into the function.

\[
f(4) = \left(\frac{4}{8}\right)^2
\]

First, simplify \( \frac{4}{8} \):

\[
\frac{4}{8} = \frac{1}{2}
\]

Then, we compute \( \left(\frac{1}{2}\right)^2 \):

\[
\left(\frac{1}{2}\right)^2 = \frac{1}{4}
\]

Thus, \( f(4) = \frac{1}{4} \).

The final answer is

\[
\boxed{\frac{1}{4}}
\]
