If you put a sheet of 216 on your lens you'll get nothing but a white-ish image :P
as John pointed out you're speaking of lighting gels.

As a rule of thumb longer lenses "accentuate" the diffusion so you'd use a lighter filter. But at the same time you have to decide how many details you want to see, wide shots may need more details than a close up and those are (generally) made with a wider lens...so you'll go with heavier diffusion because it's a wider lens or a lighter difusion because it's a wide shot? Test (and taste) may be the only answer.

Hope this helps, ciao.
