Corner radius and smoothing in Figma - Cell-by-Cell Formula Trace

Sample Data

This data shows different shapes with their corner radius and smoothing values in Figma.

Cell	Value
A1	Shape
B1	Corner Radius
C1	Smoothing (%)
A2	Rectangle
B2	10
C2	0
A3	Rounded Rectangle
B3	20
C3	0
A4	Smooth Shape
B4	20
C4	50

Formula Trace

Effective Corner Shape = ApplySmoothing(Corner Radius, Smoothing %)

Step 1: Corner Radius = 20, Smoothing = 50%

Step 2: Calculate smoothing effect: 20 * 50% = 10

Step 3: Effective corner shape = Corner Radius + smoothing effect

    A           B               C
1 | Shape    | Corner Radius | Smoothing (%) |
2 | Rectangle|      10      |      0       |
3 | Rounded Rectangle |      20      |      0       |
4 | Smooth Shape |      20      |     50       |

References: B4 and C4 feed into the smoothing calculation.

The formula uses the corner radius from cell B4 and smoothing percentage from cell C4.

3 | Rounded Rectangle |      20      |      0       |          20            |
4 | Smooth Shape |      20      |     50       |          30            |

The effective corner shape column shows the final corner radius after applying smoothing.
