How can I get text to scale automatically on different iOS screen sizes in Webflow?

To make text scale automatically across iOS screen sizes in Webflow, you need to use fluid typography techniques that adjust font size based on the viewport width.

1. Use the Clamp() Function for Font Scaling

• Clamp() lets you define a minimum, preferred (fluid), and maximum font size.
• In Webflow, go to your Style panel, select the text element, then set the font size in the following format:
  clamp(MIN, FLUID, MAX).
  Example: clamp(14px, 4vw, 24px)
• This tells the browser: never go below 14px, grow proportionally based on 4% of viewport width, and cap at 24px.

2. Apply Font Size Using Custom Properties (Optional)

• If the Style panel doesn't support clamp directly, use Custom CSS:
• Go to Page Settings > Custom Code section.
• Inside <style> tags, define rules for your text class using the clamp() technique.
• Example: .heading { font-size: clamp(18px, 5vw, 32px); }

3. Use Webflow’s Built-in Breakpoints

• Webflow allows you to manually set different font sizes for various screen widths (desktop, tablet, mobile landscape, mobile portrait).
• Select the text block, then:
• Switch to a breakpoint view using the top bar.
• Adjust font sizes at each breakpoint to fit iOS screen sizes (e.g., 375px for iPhone 12/13, 414px for iPhone Pro Max).

4. Combine Clamp() with Custom Breakpoints (Advanced)

• You can apply a clamp() value at the base breakpoint (desktop), then override with manual adjustments at narrower screen widths if needed.

5. Preview and Test on iOS Devices

• Use Webflow’s preview mode and resize the canvas.
• For precise testing, publish your site and check it on actual iOS devices or simulators like Chrome DevTools (Device mode).

Summary

Use the clamp() CSS function to create fluid, auto-scaling typography based on viewport width. For additional control, tweak font sizes at breakpoint levels using Webflow’s visual tools. This ensures readable, responsive text across all iOS screen sizes.
