I do have calipers, and I just measured 8 of the plugs I have in stock.  
They were ordered both as 1/8 inch and 3.5mm plugs, and they all measure 
0.135 inches.

Unless you have very old true 1/8 inch plugs (likely mono), I don't 
believe you have any fit problems.
The current "1/8 inch" and "3.5mm" plugs are identical.  Those are 
'nominal' dimensions.
