Pom Sizes vary by material. The size and weight of the poms also varies by the number of streamers. All show poms have approximately 1,000 streamers and are available in lengths from four inches to ten inches long. Extra large show pom sizes vary by material. Narrow cut pom streamer counts vary by material and style codes. Youth poms are smaller and have less streamers - shows have approximately 50 streamers and narrows vary by material and style. All streamer lengths and counts are approximate and refer to the actually length of the streamer. A four inch pom would be approximately 8" in diameter. Please refer to the charts below for streamer counts and sizes available.
