The red is 5 3/4" x 8". I scored it so that there are two 3 1/2" sections and a 1" section. I used the SU two hole punch to get the holes for the yellow hemp. When you insert the mini popcorn bag you can gently pull the holder together so that your holes line up. The yellow box is 2 3/4 x 3 1/4 ane the white box is 2 1/2 x 3. Let me know if you have any more questions. I'm glad you like it!
