This question already has an answer here:

I have an AF-S Nikkor 18-140mm 1:3.5-5.6 G ED lens. I have lost the cap. Wikipedia says the lens diameter is 69mm. I cannot find a 69mm cap online. The best I can do is 67mm. Can anybody shed any light on this. Thanks. I would like to buy one soon.

The filter size is what you need to know, which for that lens is 67mm.

The Nikon brand lens cap is the 67 mm snap-on Front Lens Cap LC-67.
