+# 1.4.4 Resize Text
+
+- Level: AA
+- Guideline: 1.4 Distinguishable
+- Principle: 1 Perceivable
+
+## What it is
+
+Except for captions and images of text, text can be resized without assistive technology up to 200 percent without loss of content or functionality.
+
+## How to test
+
+- Check: Except for captions and images of text, text can be resized without assistive technology up to 200 percent without loss of content or functionality.
+- Use the sufficient techniques below as acceptable methods when applicable.
+- Confirm none of the common failures apply.
+
+## Sufficient techniques (W3C)
+
+- G142: Using a technology that has commonly-available user agents that support zoom
+- Ensuring that text containers resize when the text resizes
+- using measurements that are relative to other measurements in the content
+- C28: Specifying the size of text containers using em units
+- C12: Using percent for font sizes
+- C13: Using named font sizes
+- C14: Using em units for font sizes
+- SCR34: Calculating size and position in a way that scales with text size
+- G146: Using liquid layout
+- G178: Providing controls on the web page that allow users to incrementally change the size of all text on the page up to 200 percent
+- G179: Ensuring that there is no loss of content or functionality when the text resizes and text containers do not change their width
+
+## Advisory techniques (W3C)
+
+- C17: Scaling form elements which contain text
+- C20: Using relative measurements to set column widths so that lines can average 80 characters or less when the browser is resized
+- C22: Using CSS to control visual presentation of text
+
+## Common failures (W3C)
+
+- F69: Failure of Success Criterion 1.4.4 when resizing visually rendered text up to 200 percent causes the text, image or controls to be clipped, truncated or obscured
+- F80: Failure of Success Criterion 1.4.4 when text-based form controls do not resize when visually rendered text is resized up to 200%
+- F94: Failure of Success Criterion 1.4.4 due to incorrect use of viewport units to resize text
