Understanding Corner Radius and Smoothing

In Figma, what does increasing the corner radius of a rectangle do?

A It makes the corners more rounded by increasing the curve size.

B It changes the color of the corners to a lighter shade.

C It adds a shadow effect to the corners.

D It sharpens the corners making them more pointed.

💡 Hint

Think about how the shape's edges change when you drag the corner radius slider.

Increasing the corner radius rounds the corners by enlarging the curve radius, making edges smoother.

Effect of Smoothing on Corners

What is the effect of increasing the smoothing value on a shape's corners in Figma?

A It rotates the shape clockwise.

B It increases the thickness of the shape's border.

C It fills the shape with a gradient color.

D It changes the corner type from sharp to smooth, creating a more natural curve.

💡 Hint

Smoothing affects how the corner curves look, not the border or fill.

Smoothing adjusts the corner's curve style, making it look more natural and less angular.

Visualizing Corner Radius and Smoothing Effects

You have a rectangle with a corner radius of 20 and smoothing set to 50%. Which visualization best represents this shape?

A A rectangle with sharp corners and no curves.

B A rectangle with small rounded corners and jagged edges.

C A rectangle with moderately rounded corners and smooth, flowing curves.

D A rectangle with very large rounded corners and no smoothing effect.

💡 Hint

Think about how both corner radius and smoothing combine to affect corner shape.

Corner radius sets the roundness size, smoothing controls curve softness, so 20 radius and 50% smoothing produce moderately rounded, smooth corners.

Adjusting Corner Radius and Smoothing for UI Buttons

You are designing a UI button in Figma. The design requires the button corners to be rounded but with a natural, soft curve rather than a perfect circle. Which settings should you choose?

A Set corner radius to 12 and smoothing to 70%.

B Set corner radius to 0 and smoothing to 0%.

C Set corner radius to 50 and smoothing to 0%.

D Set corner radius to 12 and smoothing to 0%.

💡 Hint

Natural soft curves require some smoothing, not zero.

Setting a moderate corner radius with high smoothing creates rounded corners with soft, natural curves suitable for UI buttons.

Troubleshooting Unexpected Corner Shapes

You set a corner radius of 30 on a rectangle but notice the corners are not as rounded as expected. You also set smoothing to 0%. What is the most likely cause?

A The rectangle's fill color is affecting corner appearance.

B Smoothing is set to 0%, so corners remain angular despite the radius.

C The corner radius value is too high and causing errors.

D The shape is locked and cannot update corner radius.

💡 Hint

Think about how smoothing affects the shape of corners beyond radius size.

With smoothing at 0%, corners keep a sharp transition even if radius is large, so corners appear less rounded.
