Grill covers are not just made generically so you have to either stretch out the cover to get it on, or tighten it to fit to your grill. Grill covers are sold by either measurement fitting or exact fitting. For example, if your grill’s measurements are around 56” x 21” x 38”, you can find a grill cover around that size to fit to your grill as it you would like it to. This way, you can choose how your grill cover fits. These grill covers are not made to look exactly like your grill, but just to cover over them, so it is best for you to choose the size and shape that pleases you and fits your grill the best, along with the correct size.
Also, you can get a grill cover according to its exact fitting. The manufacturer or company that made your grill usually makes grill covers that go exactly with the grill’s dimensions, shape and body, and overall style. This way, your cover is shaped precisely like your grill and portrays what the grill’s external form looks like without taking off the cover. This is most likely the more attractive out of the two because there is no overhang of the cover or odd shaped sides if it just thrown on and tied down. Exact fitting is easy to use because it slips right on to the grill and conforms to its shape automatically. Even though there are two different types of sizing, each one does a sufficient job in covering and protecting its grill underneath.
