AB - <jats:title>Abstract</jats:title> <jats:p> We quantify pulsar timing array (PTA) sensitivity to anisotropy in the gravitational-wave (GW) background using the cross-correlation-based Fisher information matrix in the pixel and spherical harmonic bases. We use a set of simulations to empirically determine scaling relations of a PTA’s sensitivity to anisotropy with the number of pulsars <jats:italic>N</jats:italic> <jats:sub>psr</jats:sub> in the array, the error <jats:italic>δt</jats:italic> on the times of arrival, the frequency <jats:italic>f</jats:italic> <jats:sub>GW</jats:sub> of the GWs, and the angular scale ΔΩ of the anisotropy. The sensitivity scales approximately as <jats:inline-formula> <jats:tex-math> </jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:msubsup> <mml:mrow> <mml:mi>N</mml:mi> </mml:mrow> <mml:mrow> <mml:mi mathvariant="normal">psr</mml:mi> </mml:mrow> <mml:mrow> <mml:mn>0.8</mml:mn> </mml:mrow> </mml:msubsup> </mml:math> </jats:inline-formula> , <jats:italic>δt</jats:italic> &
