What if we came up with a list of possible "Maximum Heights" and "Maximum Spread" options, and migrate the data into that?
...
The only downside is that we'd lose a little bit of the freedom that a text box brings. You'd have to select the closest maximum height.
Are you saying that the "Maximum Height" field would be a radio button or a list of specific heights?
Why not make it a
number, selected with a slider or a numeric input field?
Perhaps the input field could allow feet, inches, cm or meters, then convert to something consistent internally (like inches) for searching? The display could show inches for values less than 2 feet, and feet above that.
