The only way to measure a Fire Basket is this way....
Measure it from Side To Side.
You don't measure it this way ( along the front curve ).
That is the incorrect way.
You measure it from Side To Side and you will notice, for example, this is a 16 inch fire basket, but it will always be less the 16 inches to cater for your regular sized fireplace.
That way then, it will fit in properly.
It will always be slightly smaller than the actual size it says on the Fire Basket.
