If you do not have an oval sticker of approved dimensions, this may help!
You may, if you wish, display the Euro symbol and GB national identifier on the number plate. This will get rid of the need for a separate GB sticker when travelling within the EU.
The symbol must meet the EC Council Regulation 2411/98 which states that:
the height must be a minimum of 98mm;
n the width must be a minimum of 40mm (maximum
of 50mm);
the background must be of retro-reflecting blue
with 12 retro-reflecting yellow stars at the top; and
the distinguishing sign of the Member State (GB)
in retro-reflecting white or yellow.
