An A3 collage is an excellent choice for creating compact posters and signage. With dimensions of 297 millimetres by 420 millimetres, this size is perfect for showcasing a variety of images and text in a visually appealing arrangement. This format allows ample space to include detailed designs while maintaining a manageable display size in smaller environments, such as classrooms, cafes, or community bulletin boards.
This post will outline simple steps to create a collage on an A3 sheet. As a demonstration, we will showcase two photo collages. Here's a tutorial for making a collage of any size.
Here's what you'll need to get started:
- A selection of photos saved on your computer, whether you're using a Mac or a Windows PC. These images will be the foundation of your collage.
- TurboCollage software. If you haven't downloaded it yet, don't worry! You can quickly grab it and install it from here.
- An A3 sheet if you intend to print your collage.
- A printer capable of handling A3 size if printing is in your plans.
With these items on hand, you'll be all set to create your collage! Let's go through the steps to create a collage.
Creating an A3 Photo Collage with TurboCollage
With TurboCollage, you can easily design stunning A3 photo collages in various styles. The first step to get started is to set the collage size.
Setting the Collage Size to A3
To set the collage size, open TurboCollage and head over to the Layout section found under the Settings tab. From there, simply select A3 from the Size drop-down menu.

If you prefer, you can also specify the size manually by clicking on the "Set Custom Size..." button in the Layout section.
The A3 dimensions you need are:
- 297 mm x 420 mm
- 29.7 cm x 42 cm
- 11.69 inches x 16.54 inches
When you set the resolution to 300 pixels per inch, the dimensions in pixels will translate to 3508 px x 4962 px. This is calculated by multiplying the dimensions in inches by the resolution (11.69 inches multiplied by 300 for width and 16.54 inches multiplied by 300 for height).

You can create your collage in either Landscape orientation (420 mm wide and 297 mm high) or Portrait orientation (297 mm wide and 420 mm high).

Having established the collage size, let's explore how to create a variety of A3 collages:
