This recipe requires 900g of chopped pumpkin. This is the total amount required once the seeds and inside stringy flesh have been removed. A medium-sized pumpkin will be perfectly fine, but you may need 2 if they are very small. In any case, you might end up with leftover pumpkin. This can be kept in the fridge and used the next day for toasting, mash, purees, cookies, cakes etc.
