Q1: Why does my hollow circle disappear completely when I click transparent fill?
A1: A shape disappears if the border weight slider is still set to zero when the fill is removed. To make the outline visible, click the border style tool on the top bar and increase the stroke weight before or right after choosing the transparent color tile.
Q2: Can I adjust the inner diameter without changing the outer border size?
A2: Yes, simply by adjusting the border weight slider. Increasing the numerical stroke value expands the line thickness inward and outward simultaneously, narrowing the empty center hole while keeping the outer bounding box stable.
Q3: How do I create a dashed or dotted hollow circle?
A3: Select the circle, open the border style tool on the contextual top bar, and pick the dashed or dotted icon right next to the solid line option. The border weight slider controls the thickness of each individual dash or dot across the ring.
Q4: Why does my border thickness change when I resize the shape?
A4: Canva scales border strokes proportionally when you drag the corner handles of a shape. If you need to lock your borders to a uniform width across multiple differently sized circles, select all of them simultaneously and enter your target value into the border weight input field.
