Question: what size are the boards
Document: They are very serviceable, and there is a size for virtually every application. They look very nice sitting next to the older cutting boards. They dress up the kitchen.
I really like these cutting boards. They are a handy size and extremely durable. Love the fact they are non-slip and you can throw them in the dishwasher, unlike heavy wooden cutting boards. They are great!
My sister lives in an apartment with extremely limited counter space and the size of the cutting boards are perfect - she gets to pick the size suited to the job at hand. The quality is awesome and she loves that they go into the dishwasher without a problem.
Awesome cutting boards. A little on the small size but that's fine (I should have paid more attention to the description). All in all a great purchase. I love that they're dishwasher safe and have a groove to catch liquids from spilling off the board. I'm very pleased.
Great compact cutting boards, right size fior dishwasher and with the choice of  3 sizes to choose from small to medium size. For me it was the stain resistance &#34;Beetroot Test&#34; that has won me with these boards, so many times I have bought  cutting boards with food stains after the I first used them. Highly recommended.
LOVE this trio of boards! Each size is so useful for all manner of cutting jobs! Love the fact they are two-sided with a &#34;sauce channel&#34; on one side, flat on the other AND the non-slide grippers on each end. Would love to have one more in a slightly larger size!Yes, I would recommend these for every kitchen! Very versatile!
This is a very nice set of cutting boards that I can use in my kitchen without it taking up a lot of space. I have been eating a lot of fruit lately and I wanted a small cutting board that I could use so that I wasn't having to cut directly on the counter. The smallest size cutting board is perfect for what I am using it for. And it washes very nicely in the dishwasher.
I expected these boards to have a deeper groove, they are ordinary at best and the grooves are very disappointing in size, I am not impressed, sorry. I bought them for my husband as he wanted nice boards for cutting meat and collecting meat juice and I was very disappointed to be giving him these as part of a gift. Don't want to bother to send them back so I put them in the cuboard with all the others. The color is bright so that was the only plus.
Perfect compliment to my larger cutting boards, these are sized to eliminate that constant washing and reusing the large boards, just pull out the size you want, trim meat for a sandwich, chop some veggies and then cut the sandwich on the same small board. Helps with the size of the washer loads, these are a fine addition to any kitchen. The non-skid side is useful and the deep trough helps contain the juices from lemons, oranges, tomato's etc.
I got these because I needed to replace my other contaminated plastic cutting boards. I'm celiac and needed these boards to stay gluten free for my health. I love them! They really don't slide on the counter and are easy to wash. I only wish I could get one more in an even larger size. Definitely buy these cutting boards. The company even sends you dozens of free recipes in your email after you buy them, a nice bonus!
Answer: The largest is 14 inches by 8 1/2 inches. The middle one is 11 1/2 by 7 inches, and the smallest is 10 by 6 1/2 inches. They are smaller than I thought they would be but I find them very useful. Plus, they don't seem to stain like my old ones did.
