I'm about to buy a new portfolio in preparation for some interviews. I'm wondering whether to buy A4 or A3. My thoughts are that A3 can look studenty, costs so much to get the pages printed, but you can present larger images. A4, is this too small to show off my work? would be more cost effective as I can print on my home printer and choose my own paper. If anyone can tell me what they use and what they think is more professional it would be much appreciated. Cheers.
