The ancient Macedonian cavalry lances seem to have more than 6' (1.8 metres) of wood ahead of the hand, and are balanced pretty far back.


I am allergic to hay and horses, but I think cavalry fighting can be different because you can use the speed of the horse to drive the lance and your arm just has to put the point on target. So most people can probably use a longer lance on horseback than they can use on foot.
Some of those late medieval Italian infantry with rectangular shields have pretty long spears.
Spear and shield are not so popular today, and long spears are annoying to play with, but does anyone have thoughts on the practicality of using 10' to 12', properly tapered or barreled spears in one hand?
What is the maximum length of spears in scajun heavy fighting? They have to be rattan or sometimes fibreglass right? A lot of historical spears have external socket diameters around 20-25 mm (3/4" to 1") and were about 30-35 mm (1 1/4" to 1 1/2") diameter at the thickest part, whether that is the butt end or about 2/3 or 3/4 back from the point like Wade's pikes. And heads can be surprisingly light, around 150 grams is common for a big spearhead although 250 grams is not unheard of.
