Finding your RAM amount on Windows

The fastest way is to right-click "This PC" or "My Computer" on your desktop, then select "Properties." A window opens showing your system information — look for the line that says "Installed RAM" and you'll see the number in gigabytes (GB). That's your answer.

If you don't see "This PC" on your desktop, open File Explorer (the folder icon on your taskbar), then right-click "This PC" in the left sidebar and choose "Properties." The same information appears in the same place.

A second method works if the first doesn't: press the Windows key and the letter R at the same time to open the Run box, type msinfo32 and press Enter. Look for "Installed Physical Memory" in the window that opens — that's your RAM.

Finding your RAM amount on Mac

Click the Apple menu in the top-left corner, then select "About This Mac." A window appears showing your system information. Look for the line labeled "Memory" — the number shown is your RAM in gigabytes.

That's the only step. Macs display this information more directly than Windows does, so there's no second method needed.

Key Takeaways

  • On Windows, right-click "This PC" and select "Properties" to see "Installed RAM" displayed in gigabytes.
  • On Mac, open the Apple menu and choose "About This Mac" to find the "Memory" line showing your RAM.
  • RAM is always measured in gigabytes (GB), and the number you see is the total amount your computer has.
  • You don't need to install anything or restart your computer — this information is always visible in your system settings.

Why you might want to know your RAM

RAM is the memory your computer uses while programs are running — it's different from storage space. Knowing how much you have helps you understand whether your computer can handle the programs you want to use. A video editing program or a game might need 8 GB or 16 GB to run smoothly, so checking first saves you from buying software that won't work well on your machine.

RAM also helps you troubleshoot slowness. If your computer is running slowly and you have only 4 GB of RAM while running multiple programs, that's often the reason. Knowing the number lets you decide whether upgrading RAM would actually help.

What the numbers mean

RAM comes in amounts like 4 GB, 8 GB, 16 GB, or 32 GB. More RAM means your computer can run more programs at once without slowing down. A computer with 4 GB can handle basic tasks like email and web browsing. A computer with 8 GB handles those tasks plus some video editing or gaming. A computer with 16 GB or more handles demanding work like 3D design or running many programs simultaneously.

The number you see is the total amount installed. You can't have "half" of your RAM active — it's either there or it isn't. When you check your RAM, you're seeing the full amount available to your computer.

Checking RAM on Linux

Open a terminal window and type free -h then press Enter. The output shows your RAM in a table format. Look at the row labeled "Mem:" and the column labeled "total" — that's your total RAM in gigabytes.

A simpler visual method: open your system settings or system monitor process (the name varies by Linux version), and look for a "Memory" or "RAM" section. The total amount is displayed there.

Checking RAM on your phone or tablet

On an iPhone or iPad, go to Settings, then General, then About. Look for "Memory" — that's your RAM. iPhones and iPads typically have between 4 GB and 8 GB.

On an Android phone, go to Settings, then About Phone, then look for "RAM" in the list. Some Android phones show this under "Device Information" instead. Android phones typically have between 4 GB and 12 GB of RAM.

Phone RAM works the same way as computer RAM — more RAM means the phone can run more apps smoothly without slowing down. However, you can't upgrade phone RAM the way you can with some computers, so the amount is fixed when you buy the device.

What to do if you can't find the information

If the steps above don't show your RAM, try looking at your original purchase receipt or the box your computer came in — the specifications are usually listed there. You can also search online for your exact computer model and "RAM" or "memory" to find the specifications.

Another option: contact the manufacturer's support line with your computer's model number. They can tell you the RAM amount in seconds. Your model number is usually on a sticker on the bottom or back of your computer.

Frequently Asked Questions

Is RAM the same as storage space?

No. RAM is temporary memory your computer uses while programs are running — it clears when you shut down. Storage is permanent space where your files, photos, and programs live. You need both, but they're different things. A computer might have 8 GB of RAM and 256 GB of storage.

Can I add more RAM to my computer?

On many desktop computers and some laptops, yes — you can buy RAM modules and install them yourself or have a technician do it. On newer laptops and all phones, RAM is built in and can't be upgraded. Check your computer's manual or search for your model number plus "upgrade RAM" to learn about yours can be upgraded.

Why does my computer show less RAM than I bought?

Some RAM is reserved for your graphics card and system functions, so the amount shown in "Installed RAM" is slightly less than the physical amount you have. If you bought 16 GB, you might see 15.9 GB or 15.8 GB — this is normal and not a problem.

Does more RAM make everything faster?

More RAM helps when you're running many programs at once or using programs that need a lot of memory. If you're just browsing the web or checking email, adding RAM won't make a noticeable difference. RAM only helps with the specific problem of not having enough memory.
