What is the standard size of a heat register?
The most common sizes are 4″x10″, 4″x12″, 6″x10″, and 6″x12″ in medium-sized rooms such as bedrooms and dining rooms. Smaller sizes may be found in areas such as laundry rooms, bathrooms, and hallways.
How do I know what size vent cover to buy?
In many cases you will need to size down the cover to ensure the cover and its accompanying border will fit your duct. This is done by subtracting the size of the border (typically 1″-1.5″) from the opening size. e.g. a 10″x4″ duct opening that butts up against a wall can be covered by a 10″x3″ cover.

Where should heat registers be placed?
Supply register vents should be in every room as well. Located on the outer walls, under windows, in the ceiling, or on the floor, placement depends on the heating or cooling system as well as the construction of the home. Supply vents help change the room temperature to your desired heat or cool setting.
Should return vent be high or low?
For optimal efficiency, it’s ideal to have return registers installed. To ensure efficiency during the cooling season, your home should have high registers. High return registers draw hot air that rises to the ceiling back into the system to repeat the cooling cycle.
