Ten 335cm wide – which outwell extension? : camping


I have a Vango tent that is 335cm wide – looking to pick up an outwell extension in either size 3 (340 cm wide) or size 4 (360 cm wide) – which do you think woudl be a better fit?

I did actually have a Size 3 on its way at a very good price but the courrier has lost it and there are no more in stock from that retailer in size 3 which is why I’m considering a 4. But also maybe having 12.5cm each side might be helpful? Rather than 2.5cm!

Thanks for help!
