You found a glass dining table set 4 chairs online, and now you're staring at the checkout button. Stop. I almost bought one last month, and the only reason I didn't was a friend who already owns one. She gave me a list of questions she wished she'd asked. Here's the short version.
Is the glass clear or frosted?
Clear glass shows every smear. Every child's handprint. Every water ring. If you have kids or eat messy food, clear glass will make you insane. Frosted glass hides more, but it also hides the table's shine. I'd still pick frosted if I had a household of folks who don't wipe down. But that's a texture thing — see it in person if you can. Stores often have a floor model.
Measure the base, not the top
You're thinking about the glass top, but the base is what kills you. A glass top can be 60 inches wide, and the base can be a slim pedestal that leaves leg room. But some sets have a base that's nearly as wide as the top. That means chairs can't tuck in all the way, and you lose an inch of clearance around the table. Pull out a chair, sit, get up. If the base is in the way, it's a no.
Also measure the base depth. I've seen sets where the base sticks out so far that you can't push the chairs under. That's a dealbreaker for small spaces.
Are the chairs actually comfortable?
You'll sit in these chairs for hours. Maybe not all at once, but over time, if the seat's too shallow or the back's too straight, you'll feel it. Look for a seat depth of at least 17 inches. And check the back — some chairs have a weird angle that makes you slouch. Sit in the actual chair if you can. If you're buying online, read the dimensions, not just the reviews. Reviews are full of "looks great" but not "my back hurts after 20 minutes."
What's the glass thickness?
Most glass tables are 8mm or 10mm. 8mm is standard, fine for everyday use. But if you plan to lean on the table, 10mm feels sturdier. And check the edge — a beveled edge is less likely to chip than a sharp one. I've seen a table edge that looked like a chisel. Not safe.
How will you clean it?
You'll need a glass cleaner that doesn't leave streaks. I've used vinegar and water, but it still streaks on clear glass. Get a microfiber cloth, not paper towels. Paper towels leave lint. And don't use ammonia-based cleaners on tempered glass — it can weaken it over time. That's not a myth.
That's it. Five questions. If you're still unsure about sizing, I Bought a Pub Table Set for 2 and It Was Too Big for the Room — that was my first mistake.

And if you're wondering about materials, Cherry Wood Dining Room Set: The Rub Test That Saved Me $500 shows why a wood table might beat glass in some homes.
A glass table set isn't for everyone. If you've got a toddler, a clumsy partner, or a friend who always knocks over water, run. Get a wood or laminate top. Glass is gorgeous, but it's not forgiving.
