How wide is that flat surface minus the humped boarder.

If by "how wide", you mean the diameter of the flat surface inside the raised rim; the answer is 12 inches.

Not very wide. I'd say about 14". And we only extended it to 7'. It's probably worth about we paid for it, but not any more.

The back end is straight across and is 15 inches wide. The front end is rounded, parabolic shaped and is 3 1/4 inches wide near the end. The overall board length is 4 1/2 feet in length. These are not EXACT measurements, but reasonably close. NOTE: The measurements were taken with the cover attached to the board, so allow for that. Hope this helps you. TFB

At its widest point, it's about one inch. Maybe an inch and a half. And it gets smaller as it goes up and ends at about a half inch.

It is 3 feet wide, and rou don't need much space for the glide, a few inches each way. When fully reclined it is approx. 66 inches.

3 and 3/4 inches and there's a support leg in the middle not just the four corners. (Different but close answers probably depend on the surface)

8" solid piece. Flat. No indentations, textures or patterns. Hope this helps.

I don't have it in front of me, so this isn't exact, but it's about an inch, maybe an inch and a half, wide.

The widest part of the top board is 3.5 inches. It tapers down on both sides to 3 1/8 inches at a point that is 6 inches from the center of the board.

The board is some type of hard plastic much like a kayak. Uncertain of board width, perhaps 21/2-3 feet. It is wide enough to stand with feet side by side facing forward with plenty of room to balance. I did order a better quality adjustable paddle to accommodate the different heights of users. Great for recreational use.

The width of the strip at the widest end (the upper rounded part) is 2". The straight lower part is 1 1/2" wide.

I actually don't know as I don't have a surface, however I'll take the dimensions down and measure it up when I get home and post an answer for you :)

Just measured it. Inside flat surface, before the side curve starts, is 16.5" across.

I'm not the best with measurements but I would roughly guess about 1.5'x2' its about the size of the back board

15 1/2-inches at base (widest part) tapers slightly towards top. No protrusions.

With a ruler and laying flat its roughly 7" X 3.5" the width tapers toward the front as seen in the pics...It also allows for a fair amount of expansion..
