How Big Should My Cucumber Seedlings Be Before Transplanting?

How big should my cucumber seedlings be before transplanting? The general rule of thumb is that when a seedling has three to four true leaves, it's large enough to plant out in the garden (after it has been hardened off). When you plant a seed, the first leaves to emerge are the cotyledons. These leaves will look different from leaves that will grow later.
