Many recipes for yeasted doughs tell you to let the dough rise until it has doubled in size, but unless you're a pro baker, it's kind of hard to eyeball. This trick with a mixing bowl will help. Photo by Lenore Edman.
Several factors, like room temperature and placement, can affect how long it takes for dough to rise. If you're making some dough that needs to rise to "double its size", Sarah Jampel at Food52 suggests you just plop it into a bowl that's roughly double the size of the dough. When the bowl fills up, you know it's ready. If your bowl is a lot larger than your ball of dough, you can stick a piece of tape on the inside to mark where about double its size would be.
