The phrase "a width of approximately" is correct and usable in written English.
It can be used when specifying a measurement that is not exact but close to a certain value.
Example: "The fabric has a width of approximately 60 inches, making it suitable for various projects."
Alternatives: "a width of about" or "a width of roughly".
