Understanding Layer Blur Effect

What does applying a Layer Blur effect do to a selected object in Figma?

A It blurs only the fill color of the object, leaving strokes sharp.

B It blurs only the strokes of the object, leaving fills sharp.

C It creates a shadow effect behind the object without blurring.

D It blurs the entire object including fills, strokes, and any effects applied.

💡 Hint

Think about what happens visually when you apply a blur to a whole layer.

Layer Blur applies a blur to the entire layer, affecting fills, strokes, and any effects, making the whole object appear blurred.

Using Layer Blur for Backgrounds

You want to create a frosted glass effect behind text in Figma. Which approach using Layer Blur is correct?

A Apply Layer Blur to a rectangle behind the text with a semi-transparent fill.

B Apply Layer Blur directly to the text layer to blur the text itself.

C Apply Layer Blur to the entire frame containing the text and background.

D Apply Layer Blur only to the text stroke to soften edges.

💡 Hint

Frosted glass effect blurs the background behind the text, not the text itself.

Applying Layer Blur to a semi-transparent rectangle behind the text blurs the background, creating the frosted glass effect without affecting text clarity.

Effect of Increasing Blur Radius

What visual change occurs when you increase the blur radius in a Layer Blur effect in Figma?

A The object’s edges become softer and the blur spreads further from the object.

B The object’s stroke thickness increases without affecting blur.

C The object becomes more transparent but edges stay sharp.

D The object’s color saturation increases while blur stays constant.

💡 Hint

Think about what happens when you increase blur strength in photo editing.

Increasing the blur radius makes the blur spread wider and edges softer, making the object look more out of focus.

🔧 Formula Fix

Troubleshooting Layer Blur Visibility

You applied a Layer Blur effect to a shape but see no visible blur. What is the most likely reason?

A Layer Blur only works on text layers, not shapes.

B The shape is locked, preventing effects from showing.

C The blur radius is set to 0, so no blur is applied.

D The fill color is white, which disables blur effects.

💡 Hint

Check the blur radius value carefully.

If the blur radius is zero, the blur effect is effectively off, so no blur is visible.

Layer Blur Impact on Performance

In a complex Figma file with many layers, what is the best practice regarding Layer Blur effects to optimize performance?

A Apply Layer Blur to many small layers individually for detailed control.

B Use Layer Blur sparingly on grouped layers instead of many individual layers.

C Avoid using Layer Blur entirely as it always crashes Figma.

D Apply Layer Blur only to hidden layers to reduce rendering load.

💡 Hint

Think about how effects on many layers affect rendering speed.

Applying Layer Blur to grouped layers reduces the number of effects Figma must render, improving performance.
