Our Chimenea covers are designed to fit over a small to midsized Chimenea. In order to make sure that you get the correct size and that you achieve a perfect fit, please refer to the illustration on the left and follow these simple instructions: Measure the height of Chimenea from the bottom up to the highest point. This is a straight line from the top edge of the Chimenea to the base. Measure the diameter of the Chimenea. This is a straight line across the center of the Chimenea base-- not around the base.
