We recommend that hosts use a tape measure to get the width and length of their space. If you are only able to offer a portion of your space, just measure the available space so that we can send you well-matched renters.
If you don't have a tape measure but the space is well lit, you could consider trying a measurement app with your smartphone. iPhones are equipped with Measure and Android users can download Measure in order to get an estimate of space size.
Simply drop the first pin where you'd like to start measuring, follow the wall or area in as straight a line as possible, and drop another pin where you'd like to stop measuring. This will give you an estimate of that measurement, and a better idea of exactly how much space you have available!
