The general rule of thumb is: you can estimate one more digit past the smallest division on the measuring device. If you look at a 10mL graduated cylinder, for example, the smallest graduation is tenth of a milliliter (0.1mL). That means when you read the volume, you can estimate to the hundredths place (0.01mL). Portion of a 10mL graduated cylinder Use the bottom of the meniscus to determine the volume in the 10mL graduated cylinder. Since the smallest division (graduation) is a tenth of a milliliter, we can estimate to a hundredth of a milliliter (0.01). 3.87mL
You don't really need a graduated cylinder, all you need is enough depth to let the hydrometer float at the ending gravity. Measure your hydrometer from the bottom (weighted end) to the 1.0 scale and get one at least that length. Diameter is up to you but the larger the diameter the more wort/beer you need to fill it.
