Not always the longest side but usually lengthwise along the roll would be considered 0 deg.But then you also have the orientation of your part or piece which is probably the more important thing when setting up/layup your fibres/layers/plys etc. For me then 0 degrees would be the lengthwise or longer direction of your piece or mould. For a tube 0 is lengthwise, etc.

For a tube 0 is lengthwise, etc.The layup calls for +/-45 strips which i considered to be cut at +/-45 from my presumed 0 direction. the other guy was following the fiber direction as his 45, so cutting it parallel to the edge of the roll.
