DIY Green Screen: A Guide on How to Make a Green Screen

Many Hollywood productions rich with special effects rely on green screens for nearly every scene, but amateur and professional filmmakers working with a lower budget can also make use of this technology. However, the key is knowing how to make your own green screen with the materials available to you, but with some creativity and the right equipment, you can make your DIY green screen on a shoestring budget.

Here we'll go over what you need to make a green screen for chroma key backgrounds, along with some steps for how to put it together.

What you need to make a green screen

Many green screen kits available today are affordable and easy to put together, but if you want to make your own from scratch, there are several types of materials you'll need. When putting together a DIY green screen backdrop, you will need:

  • Material for the green screen itself
  • Lighting fixtures
  • Stands or mounting materials

Green screen materials

When it comes to the green screen materials, you can choose from different backgrounds based on your needs.

You can use green screen fabric, which you should find at many fabric retailers, and you can cut out as much as you need. The heavier the material, the better, as it won't wrinkle as much, and you can make sure the backdrop is sufficiently covered.

You can also use a green poster board from a crafts store instead of fabric, and you can use multiple poster boards together to form a larger screen if necessary. However, avoid using a poster board with a glossy surface that could lead to light reflection issues that interfere with the editing process.

Another option is paint. You can paint a large canvas or a spare wall with green screen paint of the right hue, but make sure it has a good matte finish to keep it looking smooth. Again, avoid any glossy paints that might reflect too much light and make post-production difficult.


The right lighting will help you set the scene. You can use natural lighting, which is often the best, as filming outside in the middle of the day won't make it appear as though you're filming on a set, without any shadows appearing on the green screen. If you're not filming outside, consider using LED light stands or other fixtures depending on your lighting needs.

Mounts and stands

Mounting materials could include 3M hanging strips, thumbtacks on poster board green screens, or clothespins and clotheslines. You can also create a stand using PVC piping, in which case you will need pipe cutters or saws to cut the pipes. 

How to make a green screen

If you want to know how to make a chroma key green screen, follow these basic steps using the materials you have:

1. Determine how big the green screen needs to be

Cut the amount of fabric or other materials you need for your green screen, or join multiple pieces to form a single green screen.

2. Mount or use a stand to hold the green screen

Using PVC, you can create a stand with 90-degree elbows in the corners and pipes of the right length to hold the screen. Otherwise, you can attach the fabric with clothespins on a clothesline, hang the backdrop on a wall with nails or thumbtacks, or use hanging strips for fabric or poster boards.

3. Set up your lighting

With the green screen set up, make sure the lighting is right before you begin filming, whether using daylight or light fixtures. Then you're ready to film.


Taking these steps and using these materials can allow you to easily create your own DIY green screen with a minimal budget. Remember, you can also improvise, hanging your green screen from objects such as doors or other areas without the need for a stand. With even the most basic green screen, you can bring your imagination to life through the magic of post-production.
