Check with your airline to find out luggage size limits. Your bags cannot exceed a certain size in inches or weight in pounds if you want to avoid oversize fees.
Use a tape measure to measure the length, width and height of your luggage. Do this when your luggage is already packed; putting too much inside your luggage can extend the height of the bag significantly, making it larger than its original size.
Place your packed luggage on a scale to see how much it weighs. The general policy on most airlines is that your bag cannot exceed 50 pounds, though some airlines have different policies for international flights or on their smaller planes. If your luggage exceeds the weight limit specified by your airline, you need to remove items or pack a second bag. Checking an additional piece of luggage is less expensive than paying oversize luggage fees.
