Question: will a 12 inch cake board fit in it?  will the lid still be able to snap on or would board be  in the way?
Document: This is perfect for a Big Birthday cake and you can decorate it and still have room on the top to close the lid . It also looks good even setting on the counter and the kids can get into it and close it back up and the cake stays fresh.
Although pleased with the size, looks, and feel of the cake server, I was very disappointed when I found ants crawing between the base and the top to feast on and become lost in the icing of my daughter's beautiful cake. Still haven't figured out a way to make a gasket to provide an airtight seal, or if I should just throw the server away.
I could not fit a 6&#34; high cake under this without it touching the frosting on the top. I had to tape cardboard to the edge to lift the lid up higher and then plastic wrap the rim. Otherwise, it's grear!
We got married in September 2013 and our cake topper was in the freezer just wrapped in a lot of plastic wrap. I had been looking for a container like this that sealed for a long time but all were way overpriced. This sealable cake server fit the bill and will now keep our wedding cake its absolute freshest until it is time to thaw it out and enjoy it on our one year anniversary this September:)
The Cake holder is great! I made a 3 layer cake (9&#34; cake) and it holds it with no problem. If I made a 4 layer cake, it would also hold it with no issues. There's plenty of room still in regards spacing above and around. The clasps on both ends actually holds it tight and haven't had any problems with the latch unclasping. Very happy with this cake carrier.
So either I remove one shelf from my fridge in order to accomodate the server or else I keep it on the kitchen counter when possible. As a cake carrier it's great, large enough to fit 10 in. cakes with frosting. The usable space on the plate is 12 in. I will keep looking for a less bulky keeper I can put in my fridge.
Only reason I gave it 4 stars is because I haven't used it yet,will this weekend and will change to 5 stars if all goes well. I think it's perfect and really big enough for cakes most people make,I don't think I would want it bigger,then I would think it's way too large. I like it!
We make sugar free deserts with pudding that need refrigeration and to keep them from drying out or picking up odors that may linger we needed a storage container that would fit different widths of plates. We have a side by side and this fits nicely top or bottom shelf.
This is a great cake storage unit with a handle should you wish to take it someplace. The snap over clips hold the two sections together solidly.
I actually have not used the cake server yet but at least now I have a way to transport layer cakes to various functions. Plus, it looks like it will keep a cake fresh. Shipping was perfect, transaction went off without a hitch, and price was just right.
Answer: The seat for a plate is exactly 12 inches. The lid and the snaps close outside the 12 inch seat. There is a grove for the lid and the snaps are on the outside of the lid.  If your cake board  is not more than 12 inches all will fit. I measured this with a carpenters ruler, very accurate.
