Difficult to tell from any description but these are 1" pipes and fittings. You can find this out if you look at product pictures and can see the 1 printed on a fitting or two that is it. I was trying to match existing pipes that were 3/4 inch so disappointed when they arrived. these are decorative as well. Not the same quality as actual black iron pipe you get at any home improvement store. Good enough for shelving and legs on furniture but I definitely would not stand on these or make a chair or stool that is meant to hold someone's weight. Fit and finish about what you would expect cheap and the flanges are threaded crooked like others have stated. Also when they state the sizes and lengths they do not take into account the fittings so everything will be longer slightly.

Good price for what I needed

Size: 16'' x 43''

Perfect for the coffee table I was working on, adjust to the size I needed as I only used 2 middle pipes for a 36” table top. Good durable pipes. The down come slightly scratched up as they weren’t packaged in anything protective so I ended up spraying them with a matte black.
