Guidance for choosing a topper base
When choosing a topper, check the measurement from your hairline to where your hair loss/thinning lessens, and make sure there's enough hair at that point to secure a clip. If not, measure a little further until you find sufficient coverage for a comfortable clip in application. If in doubt, go bigger.
Toppers do not vary too much in width, most pieces are 5-7inches wide. You can check what will work for you by measuring the width near the front hairline where you expect to clip the topper into place. Most people wear their toppers up to the hairline or an inch behind.
