All bird watchers know that the better your binoculars, the more satisfying your bird watching will be. And it’s not just about magnification power. The right binoculars can make it easier to see distant birds, see them in detail, and even identify them correctly.

The size of your binoculars will determine the ease of use, the field of view, and also how comfortable you are holding them.

The shape of the binoculars is very important for birding. For example, some look shorter than others. Some are more compact. Others are durable and waterproof. All of these kinds of factors describe their size.
