This is how I ship a frame and parts, everything except the wheels. The box won't be big enough to include wheels, but stays just under the size for postage concerns. Above 24" X 44" x 8", the postage takes a huge jump. This is 23" x 43" x 8", and will keep your postage cost below 20 bucks, in the states.
Get a standard bike box from your lbs. I measure the size, taking in consideration the flaps adding 6 inches. First cut one end of the box off, about 3 inches. Then cut off the top flaps where they bend. Cut down the top corners 6 inches so you'll have new flaps along the top, after the new side is taped together. You can score along the box to help fold the new flaps. That will make the height 23".
The cut end of the box is done the same way, cut 6" to make flaps and tape them up.
The frame will just barely fit in there. The dropouts are really vulnerable, use something between them to keep them from getting bent, like a piece of 2 x 4, or an old hub bolted in would be good. A can of soup will work, as long as it keeps them braced.
I like to lay everything out, wrap the parts, and then pack everything in there so there's no movement. I save all the cardboard that was cut off the box to help pack it. Also any cardboard already in the box from the original shipping can be used. When it's sealed up, everything should be snug. The box keeps the original bottom seam and one side seam, so it should hold up well, and be used again.
