Weight of 1. 5" Thick 3-Piece Pool Table Slate?

Weight of 1. 5" Thick 3-Piece Pool Table Slate?

How much would each piece of a 3-piece, 1.5-inch-thick slate weight?

I heard from a friend that slate typically weighs 168 lbs per cubic foot. I have a 9' pool table with 1.5 inch thick slate.

My quick calculation comes back at 244 pounds for each piece of the three-piece slate. Is this correct?

Numbers used:

  • 100" x 50", and 1.5" thick, works out to 4.34 cubic feet of slate.
  • 4.34 cubic feet x 168 lbs per cubic foot = 730 lbs / 3 pieces = 244 lbs per piece.

This seems light because everyone has been telling me that the slate pieces will weigh around 400 lbs - 500 lbs each.

I am looking for any personal experience here.

    I can tell you with certainty that your calculations are roughly correct.

    The "400 lbs - 500 lbs per piece" is way high, and perhaps a more accurate value for the three pieces in total. It seems like there was perhaps a communication issue where the value they are quoting you is for all three put together (or possibly mixing up kilograms vs. pounds)?

    If we look at the official specs from a Brunswick pool table with 1.5" slate we have the following:

    8 Home options (44" x 88" Playfield) * Slate: 5-piece, 1 1/2" thick * Total Weight:1150 lbs

    I picked the first 1.5" thick listing I found, which is the 1940 Brunswick Empire poo table.

    Based on their official specs, it's 1150 lbs for the entire pool table. Even if we take the lower-end value of 400 lbs from the advice you received and multiply that by three, we already exceed the total weight of the entire pool table.

    Here are a few notes that I've collected over the years from pool table installers on the topic:

    "Generic" slate weighs 168 lbs per cubic foot (this is a published common weight). Slate for a 44" x 88" pool table is roughly 48" x 92" overall (adding 2 inches under each rail). For 1-inch-thick slate, that works out to roughly 2.56 cubic feet, which would weigh 429 lbs. So each of the three pieces would weigh about 143 lbs.

    From folks familiar with the slates used in Diamond pool tables:

    The one piece slate on a Diamond 9-foot pool table weighs 618 lbs and is 1" thick. Taking 57" x 107", and multiplying that surface to get the square cubic inch weight, that is 6099 square cubic inches at a weight of .10132 per cubic inch.

    Hope that helps.

    Thanks for you reply and most importantly your assurance that I'm not looking at 400 lbs - 500 lbs! :)

    It will make moving day much more enjoyable!
