To determine the size fireplace grate you will need, simply measure the front and back width of the fireplace along with the depth from front to back. Generally, as a guideline the size of the grate should be about 5 inches less than these measurements for optimal air flow. Other customers will want the largest possible grate that will fit in the fireplace which is also fine. As far as price is concerned, if the fireplace gets used infrequently and budget is a concern a lower priced fireplace grate will probably work fine.
