Awning size

Portnoo

Hi all, I am a very new member to The Caravan Club and relatively new to caravanning, so please excuse the inexperience in both. My question is: My awning rail measures 1000cm and I have been able to source an awning at a good price but it measures 1025cm.
Would this fit,or be a problem etc. I know 25cm does not sound alot but maybe some of you "aul hands" will put me correct. Many thanks in advance. p.s My caravan is a ABI Award Northstar 1999. Thanks again
