What is the average height/width of a card?

First of all, we recommend you to define your Feed Length by “number of cards” rather than strict height which is impacting performances.

Please find below the average width & height of a card according to your feed format and platform. It allows you to give to your partner an estimation of the feed total height/width depending on their # of cards, in case they ask.

Please provide these data as estimations/ average metrics, not as a strict commitment.
