The proper etiquette for tipping DJs at a wedding depends on a number of factors, including the size of the event and the level of service provided. In general, it is considered good manners to tip 10-20% of the total bill, with larger tips being appropriate for exceptionally good service. However, some couples prefer to give a flat fee tip instead, especially if they have worked with the DJ in advance to create a custom playlist. If you are unsure about how much to tip, it is always better to err on the side of generosity. After all, DJs are often responsible for creating an unforgettable atmosphere on one of the most important days of your life.
