With a standard subscription, is there a maximum number of members I can add to a board? And do I have to pay per member I add to my board?

Welcome to the community @Thijs Pouwels 

There is no maximum number of members you can add to a board with a Trello Standard subscription - Trello offers unlimited collaborators on the Standard plan https://trello.com/pricing. This means you can add as many people as you need to your Trello workspace and boards without any restrictions based on the number of users.
