Number Plate external sizes please

Hi im looking to put rectangular plates back on my Supra instead of square plates and was just wondering if someone could tell me the external dimensions for the front and rear number plates im after please....

Front: Im after a rectangular import size plate (or smallest legal rectangular plate)... Is it 330mm x 89mm?

Rear: Rectangular plate to fill the area in the OEM Supra rear bumper nicely. I know they are geared up nicely for square plates and normal rectangular plates would be quite narrow in this area so wanting like the one in the photo below (maybe a tiny bit longer though) would the best be 520mmx140mm? (It's a standard format numperplate I have i.e. A111AAA)

Any help would be appreciated

With the standard jspec hole cut out of the rear bumper you are going to be taller than 140mm. From memory and that is fading these days its more like a 165mm but its easy enough measured. I prefer the 330mm plate at the rear which just covers the usual hole myself preferring the car colour over yellow plastic slab but everyone is different.

Thanks for the link I had seen that post but thats more to do with character sizing as apposed to ideal size plates for supra, mainly the rear plate external dimensions im after the front im fairly sure on

Thanks mate there was so many different options of heights I wasn't sure and I guessed 330mm was somewhere near what the length would be but just wanted conformation
