The Suitcase theme allows users to increase the text size to up to 200%. When text is resized, it resizes proportionally and the layout of pages and components is not compromised.
Try it yourself!
iOS: hold down Command and tap + until the text is 200% bigger.
Windows: hold down CTRL and tap + until the text is 200% bigger.
