What size hole do weight plates have?

There are three sizes in our range. SPORTNOW metal plates have a 2.5cm hole, vidaXL cast iron plates have a 3cm (30mm) hole, and Olympic weight plates have a 5cm hole. A plate only fits a bar with the matching sleeve, so check your barbell or dumbbell handle before ordering. Our barbells range lists the sleeve size for each bar.

What is the difference between standard and Olympic weight plates?

It’s the hole size. Olympic weight plates have a 5cm (2 inch) centre hole and fit Olympic bars, such as the SPORTNOW trap bar. Standard plates have a smaller hole, either 2.5cm or 3cm in our range. The two types don’t mix, so if you own an Olympic bar, you’ll need Olympic plates to go with it.

Are cast iron or cement weight plates better?

Both have their place. Cast iron plates are slim for their weight, so you can fit more on the bar, and the vidaXL cast iron sets go up to 30kg. Cement plates are covered in plastic, so they’re quieter and gentler on floors, but they’re thicker. That limits how much weight fits on the sleeve.

What are tri-grip weight plates?

They’re plates with three cut-out handles around the edge. The handles make them easier to carry, and you can get a better grip when sliding them on and off the bar. The SPORTNOW Olympic tri-grip plates come in pairs of 2.5kg and 10kg, both with a 5cm centre hole for Olympic bars.

How many weight plates should I buy?

Buy weight plates in pairs, so the bar stays balanced. A mix of small and larger plates works best: 2.5kg plates let you go up in small steps, and 10kg or 15kg plates build heavier totals. vidaXL sells a cast iron pack of eight 2.5kg plates and a 30kg set of two 10kg and two 5kg plates.

How do I store weight plates?

Keep them on a rack or plate tree rather than stacked on the floor, so nobody trips over them. Cast iron weight plates can rust if they’re stored in a damp garage, so wipe them down after use and keep them dry. Plastic-covered cement plates handle damp better, but they still last longer stored off the floor.

Do weight plates damage floors?

They can. Bare cast iron plates will mark hard floors if they’re dropped or set down roughly. The vidaXL cement plates and the vidaXL 15kg cast iron pair have plastic covers, which are gentler on floors. Whichever you choose, put rubber mats down under your lifting area to protect the floor and cut down noise.

Weight Plates for Home Gyms

Weight plates are how you make a barbell or dumbbell heavier as you get stronger. Before you choose by weight or material, though, check the size of the hole in the middle. A plate only fits a bar with a sleeve of the same size.

Our range covers three hole sizes:

2.5cm: SPORTNOW metal plates for smaller dumbbell and barbell handles.
3cm: vidaXL cast iron plates for 30mm barbells and dumbbells.
5cm (Olympic): tri-grip plates for Olympic bars, including the SPORTNOW trap bar.

There’s a choice of materials too. Cast iron plates are slim and hard-wearing. Plastic-covered cement plates are kinder to floors. Enamel-coated steel Olympic plates have a smooth finish. Sets range from single pairs of 2.5kg plates up to 30kg sets in cast iron or cement.

Brands include vidaXL, SPORTNOW and HOMCOM.

Delivery is free on all orders to UK mainland addresses and arrives in 3-5 working days, with no hidden fees.

Checking the hole size

This is the step most people miss. Measure the sleeve on your bar, or check its listing, then pick plates with the matching hole. A 2.5cm plate won’t go onto a 3cm sleeve, and a 3cm plate will slide around loosely on a 2.5cm one. Olympic bars need 5cm plates, which are also called 2 inch plates.

If you’re starting from scratch, buy the bar first and choose plates to match it. Our barbells range lists the sleeve size for each bar.

Cast iron, cement or steel?

Cast iron plates are thin for their weight, so more of them fit on the bar. They’re the better choice once you’re lifting heavier. The vidaXL cast iron range runs from packs of eight 2.5kg plates up to a 30kg set of two 10kg and two 5kg plates. One vidaXL 15kg pair adds a plastic cover over the cast iron.

Cement plates are wrapped in plastic, so they’re quieter and gentler on the floor. They’re thicker for the same weight, though, so you’ll fit less onto the sleeve. The vidaXL cement range covers sets from 10kg to 30kg.

Enamel-coated steel Olympic plates sit in between. They’re slim, with a smooth finish that wipes clean.

Tri-grip plates

Tri-grip plates have three cut-out handles around the edge, which makes them easier to carry and to slide on and off a bar. The SPORTNOW Olympic tri-grip plates come in pairs of 2.5kg and 10kg, both with a 5cm hole.

Building up your set

Always buy plates in pairs, so the bar stays balanced. Smaller plates, like 2.5kg, let you go up in small steps, while 10kg and 15kg plates take you to heavier totals without overloading the sleeve. For dumbbell handles and sets, see our dumbbells range.

Storage and care

Keep plates on a rack or plate tree rather than on the floor, where they can trip someone up. Cast iron can rust if it’s left in a damp garage, so wipe plates down and keep them dry. Use rubber mats under your lifting area, even with covered plates.

Delivery and returns

Delivery is free on all orders to UK mainland addresses and arrives in 3-5 working days, with no hidden fees. If you change your mind, you can return your order, but the return postage is paid by you.
