For a bunch of reasons, I need to connect my electric dryer to a fresh air input source. The dryer has the typical 4 inch exhaust coming from the dryer but I am wondering what size input duct I can get away with. it would seem reasonable that if there is a 4 inch coming out, it would require a 4 inch coming in but in my situation, it would be much easier if I could go to a 2 or 3 inch input pipe due to the location of where I need to run the input. If I go less than a 4 inch input, am I basically going to “starve” the dryer and for instance increase/double my dry time?

is this to supply air for natural gas or propane? We've only had electric dryers and never have seen anything with input air.

Electric- pretty sure this has metal punch-outs on both sides and I can supply input air to either side on the lower back portion of each side. However, now looking at the dryer manual, I might have been mislead and you are right. Manual seems to suggest the exhaust can be relocated and no mention of input air.

Those are for the exhaust, I have also never seen a dryer with an inlet for fresh air. You may even have a knock in the center of the bottom of the dryer, ours is set up that way (PS, you do not ever want to do that.) Those (bottom exhaust) are an invention of the devil, sitting the dryer in place is almost impossible, though it dos allo the dryer to be flat against the wall....I guess that's why the PO of this house chose it.
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.
