Formula Trace

IF(Device = "Mobile", "375x667", IF(Device = "Tablet", "768x1024", IF(Device = "Desktop", "1440x900", "Unknown")))

Step 1: Device = "Mobile"

Step 2: Return "375x667" if device is Mobile

Step 3: Device = "Tablet"

Step 4: Return "768x1024" if device is Tablet

Step 5: Device = "Desktop"

Step 6: Return "1440x900" if device is Desktop

Step 7: Else "Unknown"

Cell Reference Map

   A       B       C
1 Device  Width   Height
2 Mobile  375     667
3 Tablet  768     1024
4 Desktop 1440    900

Arrows: Device in A2:A4 feeds into the IF formula to select Width and Height from B2:C4.

The formula references the Device column to determine which Width and Height values to use for device-specific frames.

Result

   A       B       C       D
1 Device  Width   Height  Frame Size
2 Mobile  375     667     375x667
3 Tablet  768     1024    768x1024
4 Desktop 1440    900     1440x900

The final result shows the device name, its width and height, and the combined frame size used in Figma for device-specific frames.

What is the main purpose of using device-specific frames in Figma?

easy

A. To design layouts optimized for mobile, tablet, and desktop screens

B. To add animations to your design

C. To create 3D models within your design

D. To export designs only as PDFs

Solution

1. Step 1: Understand device-specific frames

   Device-specific frames are preset sizes in Figma for mobile, tablet, and desktop screens.

2. Step 2: Identify their purpose

   They help designers create layouts that fit each device's screen size properly.

3. Final Answer:

   To design layouts optimized for mobile, tablet, and desktop screens -> Option A

4. Quick Check:

   Device-specific frames = optimized layouts [OK]

Hint: Remember: device frames match screen sizes for better design [OK]

Common Mistakes:

• Confusing frames with animation tools
• Thinking frames create 3D models
• Assuming frames only export PDFs

2.

Which of the following is the correct way to add a mobile device frame in Figma?

1. Click Frame tool
2. Select Mobile preset
3. Draw frame on canvas

easy

A. Use Rectangle tool and resize manually to mobile size

B. Click Text tool, type 'Mobile', then draw frame

C. Import a mobile image and trace it

D. Click Frame tool, select Mobile preset, then draw frame on canvas

Solution

1. Step 1: Use Frame tool for device frames

   Figma's Frame tool includes presets for devices like Mobile, Tablet, Desktop.

2. Step 2: Select Mobile preset and draw

   Selecting the Mobile preset sets the correct size automatically when you draw the frame.

3. Final Answer:

   Click Frame tool, select Mobile preset, then draw frame on canvas -> Option D

4. Quick Check:

   Frame tool + Mobile preset = correct method [OK]

Hint: Use Frame tool presets for exact device sizes [OK]

Common Mistakes:

• Using Text tool instead of Frame tool
• Manually resizing rectangles instead of presets
• Importing images instead of using frames

3.

Given a desktop frame of width 1440px and a button constrained to the left and right edges, what happens if you resize the frame to 1200px width?

medium

A. The button width shrinks to fit the new frame width

B. The button stays the same size and overflows the frame

C. The button disappears from the frame

D. The button moves to the center but keeps original width

Solution

1. Step 1: Understand constraints on button

   Constraining left and right edges means the button resizes horizontally with the frame.

2. Step 2: Effect of resizing frame width

   When the frame width shrinks from 1440px to 1200px, the button width also shrinks to fit inside.

3. Final Answer:

   The button width shrinks to fit the new frame width -> Option A

4. Quick Check:

   Left-right constraints = button resizes [OK]

Hint: Left-right constraints resize width with frame [OK]

Common Mistakes:

• Assuming button size stays fixed
• Thinking button disappears
• Believing button centers but keeps size

4.

You created a tablet frame and placed an image inside it. The image is set to fixed size but you want it to resize proportionally when the frame changes size. What is the error and how to fix it?

medium

A. You must group the image with the frame to resize together

B. The image's constraints are set to 'Fixed'; change constraints to 'Scale' to resize proportionally

C. The image is raster; convert to vector to resize

D. The frame size is locked; unlock it to resize the image

Solution

1. Step 1: Identify the problem with fixed size

   Fixed size means the image does not change size when the frame resizes.

2. Step 2: Change constraints to allow scaling

   Setting constraints to 'Scale' makes the image resize proportionally with the frame.

3. Final Answer:

   The image's constraints are set to 'Fixed'; change constraints to 'Scale' to resize proportionally -> Option B

4. Quick Check:

   Fixed size blocks resizing; use Scale constraints [OK]

Hint: Use 'Scale' constraints for proportional resizing [OK]

Common Mistakes:

• Trying to unlock frame instead of changing constraints
• Confusing raster/vector with resizing behavior
• Grouping instead of adjusting constraints

5.

You want to design a responsive dashboard that works on mobile, tablet, and desktop using device-specific frames. Which approach best ensures your design adapts smoothly across devices?

hard

A. Use one large frame and crop it differently for each device

B. Design only for desktop and scale down manually for other devices

C. Create separate frames for each device preset and use constraints to adjust elements within each frame

D. Design only for mobile and stretch elements for larger screens

Solution

1. Step 1: Understand device-specific frames for responsiveness

   Using separate frames for mobile, tablet, and desktop lets you design layouts tailored to each screen size.

2. Step 2: Use constraints inside each frame

   Constraints help elements resize or reposition smoothly when frame size changes, ensuring adaptability.

3. Final Answer:

   Create separate frames for each device preset and use constraints to adjust elements within each frame -> Option C

4. Quick Check:

   Separate frames + constraints = smooth responsive design [OK]

Hint: Use separate frames plus constraints for best responsiveness [OK]

Common Mistakes:

• Designing only for desktop or mobile and scaling manually
• Using one frame and cropping instead of designing per device
• Ignoring constraints for element resizing
