How thick and heavy are glass dining tabletops?

If you’re in the market for glass dining tables, you know that depending on the size, they can get pretty heavy. This isn’t always due to the legs or the frame. Most of the weight is contributed to by the giant glass slab on top.

It’s safe to assume that this glass tabletop requires a lot of consideration when moving and setting it down. Glass tabletops are traditionally more expensive than your engineered wood tables so you have to make sure you are being careful with the handling.

How heavy are glass dining tables? A glass table that will fit 4 adults can weigh between 40 to 60 pounds. A glass table for 6 can weigh anywhere between 60 to 80 pounds. And a glass table for 8 people can weigh 100 to 150 pounds or more.

The thickness of the glass on a glass table is important in knowing the weight of the table

It’s important to keep in mind that not all glass tables are made with the same thickness. If a glass table were thicker. The thickness of the glass slab adds quite a bit of weight to a table.

Traditionally, the thicker and heavier a glass top is, the bigger and heavier the support needs to be. The legs of these tables need to be able to hold up all that glass. And not only that, it needs to support the mid-section of the glass tabletop if the glass is really long and wide.

That is why you’ll traditionally see glass tables have legs or a frame that supports the mid-section of the glass.

The thickness of a glass tabletop also adds to the strength of the glass

When you compare the difference between a thin glass slab versus a thick glass slab, you’ll notice how much less wobbling that thick glass will portray. Thinner slabs of glass may be lighter, but the thick ones make the table very heavy.

With a heavy glass table, you get the benefit of strength. The glass would be much less resistant to breaking if it were thicker. If someone leaned on a thin glass table, you might see slight bending if you look really close. Glass doesn’t bend very well at all. The amount of tolerance to bending is so low that your thin glass table will probably shatter before you even notice it bending.

There’s another benefit to having a really thick glass table. Since really thick glass tables are heavy, it also adds to the stability of the table as well. If you had a heavy glass table, it would be difficult to push it over, tilt, or even sway.

And just like trying to push over a big and heavy person, a heavy glass table, too, will have a strong core.

What are the most popular thicknesses of a glass table?

The real question here is how thick does your glass table need to be? It depends on how you use it. Dining tables in particular need to hold a lot of weight. It needs to be able to support the designated number of elbows leaning on it during an evening dinner and all the food and plates for that meal.

The most popular thicknesses are ¼, ⅜, and ½ inches.

Keep in mind again, as the thickness increases, you’ll begin to see some substantial rise in weight.

However, the thicker and heavier a glass table is, the more attractive it becomes. Out of these 3 options, the thickest one is the ½ inch one. On any similar-sized glass dining table, it would end up being twice as heavy as the table with a thickness of ¼ inch. Glass tabletops that are ⅜ inch thickness are in between these two.

How to calculate the weight of a glass tabletop

If you’re interested to know how much the glass on a dining table weighs, you can simply do the calculations yourself. Whether you’re at the store trying to buy a brand new table or simply at home and curious about how much your own table weighs, you can calculate that.

Here’s the conversion.

Glass thickness in inchesPounds/sqft
¼ 3.27
⅜ 4.91
½ 6.54

Here are some quick steps to getting an approximation of your glass top weight.

  1. Measure the thickness of the glass table with either a caliper or a measuring tape.
  2. If the tabletop is a rectangle or square, take the length and width of the table in feet and multiply both numbers together.
  3. Multiply that result with the number on the right side of the table above that correlates with the thickness you found in step 1.

Below is an in-depth overview of the steps above.

You will need to see which of these thicknesses match the glass table you are looking at.

You’re going to need a tape measure for this or something called a caliper (You can check it out here on Amazon). These things have these beak-like ends that end up closing onto an item like a tabletop. The gap between the caliper’s mouth is a precise measurement of how thick that tabletop is.

If you don’t have one or don’t plan to get one, you can simply just eye-ball it with a tape measure. It should be close enough.

Next, you’re going to need to understand what the right column above means in the table provided. It’s talking about the number of pounds for every square foot of glass. In the case of ¼ inch tables, if you had a square slab of glass that was ¼ inches thick, it would weigh approximately 3.27 pounds.

Now all you need to do is find the area of your table using your measuring tape. If the table is a rectangle or a square, simply measure the length and width based on the footage. Take this number and multiply it by the number that corresponds to the glass thickness. In our case, 3.27.

If the table were a circular table, you’d have to get the radius. The formula is A = π r². In case you need extra help with a circular table. Here’s a video on YouTube that explains it really well.

How many people do I need to move a glass table?

Moving a glass table can be a challenge. More often than not, I highly recommend you find a second person to help you move a glass table if you ever need it.

Luckily for some, the glass slab on a table can be removed in some designs which will make the moving process a lot simpler. It still doesn’t avoid the fact that you may need two people though.

Moving a glass table has to be handled with absolute care. If you were to accidentally drop a wooden table, you might get away with just a scratch or dent. If you were to happen to drop a glass table, depending on how hard it hits the floor and what the floor is made out of, you could potentially be looking at a full-on shatter. Millions of pieces would be all over the floor and you’ve just lost a really expensive table.

If you are able to remove the glass top, then do it. Move the parts of the table with patience.

What I did with my table when I removed the top was found some strong, heavy, and soft bathroom towels. My friend and I covered the glass with as much of the towel as we could. With each person on each end, we tilted and lifted the tabletop starting on one side and rotated it straight up with each person on each end of the tabletop. We carried it over to the designated location and placed it down securely on a surface with the towels protecting the area between the floor and the glass.

The rest of the pieces were picked up and moved and reassembled.

Finally, we stood our positions on both ends of the glass tabletop, lifted and placed it on the table’s support and legs.

This was roughly a 4 to 6 seater glass tabletop.
