I see what you're saying, but -- honestly -- no one's ever going to notice this.

Do you think the threshold is too deep?

I think the dramatic appearance of the entry door with sidelights is perfection.

I think the half-circular rug looks cheap.

i think it looks fine. put some potted plants on either side and the mat pictured above

Unless it is functionally not working well, I think it is visually fine and wouldn't mess with it. New mat and be done with it!

I think it looks fine. I agree to get a new and brighter mat.

I think the current mat shape makes the door look even more inset than it is. A rectangular mat, the width of the door or wider, might help with the "depth" perspective.

IMO a pot on either side in front of the threshold would take your eye to the plants . I happen to love the look of the door so not an issue for me

The depth of the door directly correlates to how thick the wall is. The door is inset so the door can swing wide against the interior side of the exterior door.

Perhaps you are used to the shallow inset of doors on house with 2x4 framing. With the thicker walls of today's more energy efficient 2x6 framing, exterior doors will have a deeper inset. The thickness of exterior cladding also determines inset depth.

And, too, when a storm door is installed, that changes how the opening looks and disguises the actual inset depth.

Your door is fine. Echoing that the front mat needs to be replaced.

A rectangular mat, plants and a beautiful entryway fixture and you’ll forget that your door is slightly different.

The deeper door opening looks more custom, I like it as-is.
