# Defining Measurement Values

Applying measurement values to various attributes defining the dimensions (length, width) at the element level.

When authoring content you can apply measurement values to various attributes defining the dimensions (length, width) at the element level. The best practice is to define measurement values in lowercase; entering the values in UPPERCASE may cause unexpected results in the generated output.

The standard units of measurement supported by the Requirements Editor include all valid CSS measurement units: %, in, cm, mm, em, ex, pt, pc, and px. You can use both absolute units (cm, mm, in, pt, and pc), font-centric units (em, ex), the pixel (px) and percentage (%) units. If a measurement unit is entered in UPPERCASE (for example, 1PT), the Requirements Editor will accept the value but will not assemble the document in a manner that produces the desired output.
Note: The Requirements Editor will not present a validation error or any indicator that a measurement value was entered as UPPERCASE and, as a result, the output is at risk of not producing the desired results.
