Adinary Nuance

Use long for size or time that extends over a greater distance or period. It is more neutral than lengthy, which often sounds more formal or slightly negative. For time, long is the everyday choice, while prolonged sounds more formal and often suggests something unwanted. Compared with tall, long describes distance from end to end, not height.
