Hinges are the hardest-working part of a door and the part nobody notices until one squeaks or sags. The specialty options here solve specific problems: an invisible hinge hides completely when the door is closed for a clean line, while a spring hinge pulls a door shut on its own. The trade is always a little more installation fuss for the look or function you want.

Door thickness and weight drive the choice. An invisible hinge is matched to a thickness range and needs a routed mortise in both leaves, so it is a commitment, not a swap. Confirm your door falls in range before you cut anything.

Choosing well

Measure your door thickness, match it to the hinge range, and be honest about your comfort with a router before choosing an invisible model. Done right, the reward is a door that swings clean and gives nothing away.
