An angled sash brush with stiff synthetic bristles is the gold standard for cutting in without tape . Specifically, a 2.5-inch or 3-inch width is favored by professional painters for interior walls because it holds a massive amount of paint while maintaining a crisp, razor-sharp edge. If you are a beginner or working in tight quarters like closets, a 2-inch short-handled (stubby) brush gives you maximum control and reduces hand fatigue.[4][5]
