Cardboard VR viewers: the cheapest way to try virtual reality as a family
What cardboard virtual reality viewers are, which phone you need, what you can do with them and when it's worth moving up to a plastic viewer or a standalone headset.
A cardboard virtual reality viewer costs less than a cinema ticket and is all you need to find out what it feels like to "step into" a 3D image. It's the cheapest way to try virtual reality as a family before spending more, and a good way to see whether your child enjoys it (or gets dizzy).
What they are and how they work
They're a folded cardboard box with two lenses. You put your phone inside, and it shows the image split in two, one half for each eye. The lenses help the brain merge them into a single image with depth. When you turn your head, the phone's gyroscope detects the movement and the image turns with you.
Google popularised the idea in 2014 with its Google Cardboard viewer. Google stopped selling its own in 2021, but it had released the design as open source in 2019, so many brands still make compatible viewers today.
What you can do with them
- 360-degree videos, for example on YouTube: places, animals, concerts or space.
- Simple apps and games designed for phone viewers.
- Browser experiences with a viewer mode. For example, the games on VRforKidz have a "VR with phone viewer" mode: you aim with your gaze, tap the screen to shoot and hold to walk.
Which phone you need
Almost any phone from the last few years will do, but check three things:
- It has a gyroscope. This is what lets you look around. To check, open a 360-degree video on YouTube and turn your phone: if the image follows you, it has one.
- It fits in the viewer. Each viewer lists the screen sizes it supports on the box. Take off any thick case.
- It has a good screen. With lenses in front you can see the screen's pixels; the higher the resolution, the better it looks.
Bear in mind that the phone heats up and drains its battery in long sessions. Another reason to keep them short.
What they can't do
Worth knowing to avoid disappointment:
- They only track head rotation, not body movement: if you take a step, the world doesn't move with you.
- No controllers. At most, a button or tapping the screen.
- You have to hold them, unless the viewer has straps.
- Cardboard wears out with use and can't be cleaned properly, so it's best if everyone has their own.

If the cardboard viewer is a hit and you want something more comfortable for the phone, the next step is a plastic viewer with head straps: no need to hold it, it lasts longer and many let you adjust the lenses. If you want the full experience, with controllers and freedom to move, the leap is to a standalone headset such as the Meta Quest (with its age limits, which we explain in At what age can a child use a virtual reality headset?).

Frequently asked questions
Does any phone work?
Almost any recent one, as long as it has a gyroscope and fits in the viewer. Very large phones or ones with curved edges sometimes don't fit well.
Can you use them with glasses?
With many cardboard viewers it's uncomfortable or impossible. Some plastic viewers have room for glasses or let you focus the lenses. Check the product description.
From what age?
Google sets no age for its viewer, but asks that children always use it with an adult. Other manufacturers print their own age on the box. We cover this in detail in our article on ages.
