You could measure the diameter of the wire to find its gauge, then find the resistance of the coil. for example lets say the diameter is 0.122mm, or 40SWG. According to the datasheet a wire of 40SWG has a resistance of 1.48Ω per metre.
From this you divide the coil's resistance by the resistance per metre to work out it's approximate length.
I hope this is helpful.
