Size of rear numberplate on Turbo R

[chrono]

I need to order a set of new numberplates for my '96 Turbo R and wondered if anyone knew what size I need to order? I realise I could just go and measure it but the car's in storage right now.

Many thanks

Come on chaps, get your tape measures out. I would oblige, but my car is away being fettled.
