I can't really give a specific answer, but I can list some factors.
Houpelands are really more of a wool kind of a garment, ideally using something napped, springy and falling in soft folds. They were frequently lined with lightweight fur, enhancing the softness and fullness of the folds even more.
The lighter the weight of the fabric you use, the more fabric you need to acheive the appropriate silhouette and drape. For example, using a fulled or boiled wool of light to moderate weight, a houppelande that is approximately a half circle or slightly less will have the same silhouette as the paintings. In a lightweight, unlined linen, you might have to use a whole circle. In a mid to heavy linen, maybe 3/4 of a circle. Or you could line a lightweight linen or silk with heavy muslin or medium weight flannel and use a half circle.
Also a houppeland is an outer garment suitable for an environment where the temps may average around 50 to 60 degrees, so they are warm. I can only wear mine when the temp is below 65. Perhaps a lightweight linen might be cool enough to wear inside, but for it too look right, you will need enough fullness that it's more like wearing 2 or 3 layers of linen that weight.
