Auto-size a text frame

Use Typefi AutoFit to create auto-sizing text frames. For example, if a figure caption is longer than its text frame, Typefi AutoFit automatically resizes the frame to fit the entire caption and eliminate any overset text.

Apply an auto-size option to a text frame

Typefi AutoFit only auto-sizes text frames. If you want to auto-size images, use InDesign's Auto-Fit feature (Object → Fitting → Frame Fitting Options). See Using Auto Fit for instructions.

1. Select a text frame.
   
   
   
2. Open the Typefi AutoFit panel (Window → Typefi → AutoFit), and choose an option from the Auto-size menu: None, Height Only, Width Only, Height and Width, or Height and Width (Keep Proportions). 
   

What does each auto-size option do?

Auto-size option	Description
None	Does nothing and is equivalent to a normal InDesign text frame. Use this option to turn off automatic resizing.
Height Only	Enables the text frame to grow or shrink vertically.
Width Only	Enables the text frame to grow or shrink horizontally.
Height and Width	Enables the text frame to grow or shrink both vertically and horizontally.
Height and Width (Keep Proportions)	Enables the text frame to be proportionally resized.

Select a reference point on the Typefi AutoFit panel to specify the direction the text frame resizes.

You may also want to specify the minimum and maximum frame dimensions to keep the element within a specific boundary on the page. If an AutoFit maximum height limit does not constrain the frame, the frame may extend to the pasteboard limit. Also, if the frame contains an inline object whose height is greater than allowed by AutoFit or the pasteboard limit, or if it contains text that is wider than a column (due to Hyphenation Settings, nonbreaking spaces, or the No Break character attribute), the frame will extend only to the last displayable line of text.

Remove an auto-size option

To remove an auto-size option, choose None from the Auto-size menu or Clear Attributes from the AutoFit panel menu.

Choosing Clear attributes will also remove any minimum or maximum size limits.

Can I combine AuotFit relationships with an auto-size option?

Yes! When combined with AutoFit relationships, the auto-size options enable you to design adaptive elements that dynamically react to content changes (see Create AutoFit relationships).

Why doesn't my text frame ever reach the maximum width?

To answer this question, we first need to understand how auto-sizing works in InDesign, before adding any Typefi AutoFit limits.

The actual behaviour of InDesign for width auto-sizing depends on several factors. If line breaks are allowed, InDesign resizes the frame's width to completely fill it (subject to an optional minimum width) without causing overset text. This could create unexpected results if the text frame were severely underset before enabling width auto-sizing (see screenshot).

An example of a severely underset text frame before and after it was auto-sized.

Also, it's important to note that InDesign has practical limits for auto-sizing based on the pasteboard's extents (which is based on the document page size, whether the document has facing pages, and the extent of the bleed and slug area). This doesn't just apply to auto-sizing text frames but also applies to auto-sizing table cells.

For example, InDesign ignores auto-sizing (that is, it does nothing) if you enable no line breaks, and the text frame width would need to extend beyond the pasteboard to render the longest paragraph of the frame on a single line.

So, the answer to the question, Why doesn't my text frame ever reach the maximum width?, is quite complex and depends on many factors. If you're running into issues, check whether the original text frame is severely underset, if line breaks are allowed, or if the text frame width would need to extend beyond the pasteboard to render the longest paragraph on a single line.
