I'm making my first wedding cake next week and I've been asked to make a 14'' lemon cake, I already have a lemon cake recipe that I use but it's only good for an 9''. 
I was wondering if I could just double the recipe for the 14''? If not how do I go about adjusting my recipes to fit larger cake pans?
Thanks
Rachel
You may want to consider using a baking core or 3 greased and floured flower nails towards the center of the cake to ensure even baking of such a big cake. Also - use baking strips if you have access to these in the UK.
Also, as you go up in size of cake you typically use slightly less leavening, ie. baking powder, which weakens the cake structure. The Cake Bible has a good discussion on this...
What kind of cake is it - sponge or butter (Madeira)?
All the best, I'm sure it will come out fine 
Thanx Toptier for the information, I had completely forgotten about needing a core to make sure it all bakes evenly, I'm making a lemon cake which i got the recipe off youtube, my friends have really liked it as it's nice and light, luckily all of the cakes will be standing on their own so I dont have to worry about it needing to hold another 3 cakes.
I"m going to try and bake on tuesday, to make sure it comes out ok, that way I have time to make sure i get it right. I've never baked more bigger than a 10" so wish me luck and I'll let you know how it all turns out.
thanx for the help.
