Shelves longer than standard Conti board?

You can get longer lengths - the only problem is that you may have to order larger quantities and even then it may only be 10 ft ie 3.0m. I have overcome this in the past by dowelling the ends of the boards and putting the joint over a support - that way it is barely noticeable. You are usually resticted to white in the 8ft lengths by the way - colurs tend to come in 2.0m lengths. Depending on what width shelves you want you might consider floor boarding.

Ok, wow...this is terrible. First, let's change feet to inches, otherwise we'll just melt our brains. 6 feet * 12 inches/foot = 72 inches. We know that these shelves need to be consecutive even numbers, right? We'll solve this using some algebra and some logic. The first shelf would be x inches long. The next-longest shelf would be x+2 inches long, right? Since consecutive even numbers are 2 numbers apart? The next would be 2 inches longer than that. That's x + 2 + 2, or x + 4. And the fourth one would be two inches longer than that x + 6 So let's put all this together: We have four shelves, each with the following lengths x x+2 x+4 x+6 totaling 72 inches. If all those shelves put together are 72 inches long, we can do this: x + x+2 + x+4 + x+6 = 72 Now, we'll simplify, by combining like terms. 4x + 12 = 72. 4x = 60 x = 15 Sorry, but it can't be done, at least not without having some left over. You could have one shelf of 14, one of 16, one of 18, and one of 20 inches, which adds up to 68 inches, with 4 left over. But unless he wants them to be ODD-numbered lengths, this problem is unsolvable.

Dowel or biscuit lengths together for an almost undetectable join. Make sure that the join lines up with one of your supports so that it does not flex.
