There is no set time for how long a sedar meal is. A Sedar has many parts. Before the actual meal, there is the retelling of story of the exodus of the Jews from Egypt. Because of traditional prayers and readings, as well as lively discussion, this can take up to 1 hour; and that's before anyone eats. The meal itself has some customary servings. 1st eggs in salt water, gefilte fish, chicken soup, and then the main course. After dinner, there are normally plenty of deserts and then the last part of the Sedar; grace after meals. In this case, the B'rkot (grace after meals) includes, not just prayers and readings, by many joyous songs. It is not unusual for the whole Seder to take 4-5 hours.
A complete seder can last an entire evening. The "service" part of it includes prayers and readings including recounting the Exodus and incorporates foods associated with the texts including wine, matzah, sweet and bitter herbs, salt water, a roasted lamb bone, egg, and a mixture of nuts, apples and wine (there are variations) called "charoses" (ch is gutteral, not like chair). This can easily last an hour or more because after certain texts are read they may also be sung or chanted by everyone, such as the "4 questions". Once the primary service is over, there is a complete meal served. That can last another hour. THEN there are additional prayers including a grace after meals, and much singing together with the hunt for the "afikomen" ("dessert") or hidden matza.
Then again there are folks who keep it short....and at synagogues where young people are invited it can be abbreviated. Also, since many also have a second seder (on the 2nd evening), that can be shorter than the first as well. These can be an hour to two, maybe three.
It depends on how much food you have but the typical ranges are 1-2 hour just for the meal.

One of the foods on the Seder plate is the Z'roa - a roasted shank-bone of lamb or goat, or a chicken wing, or chicken neck. It symbolizes the korban Pesach (Pesach sacrifice), which was a lamb that was offered in the Temple in Jerusalem, then roasted and eaten as part of the meal on Seder night.
