How to Measure the Linear Inches of a Bow Case

As you prepare for a trip, being aware of baggage size limits can save you delays at the check-in counter and possible fees. The size limits are enforced to ensure every passenger's baggage fits on the plane and the plane isn't overweight. Security and baggage regulations are constantly changing, making it important to measure the linear inches of your luggage, including the bow case. Measuring the linear inches can be calculated after taking a few simple measurements.

      Measure the length. Position the bow case on a table or solid surface about waist high. Measure the longest side of the bow case to determine the length. Place the tape measure on one side of the case and extend the tape measure to the opposite end. Record the measurement on a piece of paper to the nearest inch.

      Measure the width. The width is the distance from the front to the back of the case and is typically the second longest measurement. Extend the tape from the front to the back and record the measurement to the nearest inch and record.

      Measure the height. The height--typically the smallest measurement--is the measurement from the top to bottom of the bow case as it lays flat on the table. Some cases might have curved sides, but most airline-approved cases will be flat. Extend the tape measure from the bottom to top and record the measurement to the nearest inch.

      Determine the total lineal length. Add the length, width and height measurements. For example, if the bow case measured 30 inches long, 22 inches wide and 8 inches tall, the overall lineal length would be 60 inches. As of November 2008, all domestic flights in the United States and Canada enforce a maximum of 62 lineal inches.
