10' posts? PT, Douglas Fir or cedar?

most hardware and wood places only have 8'ers. I have a 5' high sign and that will put it about a foot off the ground. so do i special order 10 footers $$? Or...?

Art! Hot and fresh.
+1 to what signmeup said.

10'x4"x4" and longer can be ordered, you will just have to wait ... or find a lumber yard that cuts their own stock. Places that actually sell deck supplies (not home despot and their 'lumber' department) will probably have load baring kiln dried 4x4s to the length you need.

as most 2x4s are plained they will not be a true 4x4 and will have some warping issues later since most 2x4s are cut from green pine and rarely kiln dried. I used to make cedar 4x4s (or larger) by getting the 1x6 planks and laminating to the appropriate size over what I needed and cutting down to what I needed ... couple deck screws afterwords through the middle helps it from delaminating with the elements .. that and some good adhesives. just make sure to clamp to a flat surface coated with plastic (for glue dripping) and you'll be fine.

Most of the lumber yards around here have 10' 4x4 PT, hard to believe there's not a place in your area with them.
But in any case another option is to scab two 4x4s together with some 1x PT decking and create a skirt for the the first foot or two out of the ground.
Some gorilla glue and scews and it will solid.

Your measurements are a little off. If this is to remain in the ground for any period of time, especially where you're located, you should go down 38" to 42" into the ground and pack very hard if not using cement. With these calculations, that would put your sign underground. If using cement, you should go double the depth of your frost line to be safe. Otherwise movement of the earth, rain, snow and wind will raise that thing out of the ground in no time.

Around here, you can get pressure treated in 8', 10', 12' & 16' at almost any Home Depot or Lowes. At the lumber yard, you can generally get up to 12'. However, at 12' you start to see some curving and after a year in the ground, they generally go back to their original state of what they were when growing naturally in the ground.

8' posts leave you what, 2' in the ground then?
shoot... just screw on some leg extenders (treated wood/aluminum or steel angle). getting buried in the ground anyways, so it doesn't have to look pretty.

Gino he said a 5' sign 1' off the ground so that leaves 4' in the ground.....
but that means for 3 or 4 months the bottom of the sign will be buried in the snow.

He also said the only thing available to him is 8 footers, unless he special orders and pays more. So, it sounds like he's attempting 8' posts to me.

If you're going to special order (and assuming this is a permanent sign) get cedar 6x6s. One of my pet peeves is people installing a nice permanent sign on tiny toothpick 4x4s, especially a fairly sizeable sign. Get nice cedar 6x6s, stain them with a UV-resistant stain or a solid stain, put a nice finial or ball cap on them, and give you customer something to be really proud of. The cedar will outlast pine, and you won't have to worry about it twisting in a year. They're more expensive but the look is significantly better.
