How to make a thumbnail in Scratch


Are you ready to become a coding wizard? In this tutorial, we will learn how to make a thumbnail in Scratch, a fun and interactive programming language. With Scratch, you can create your own games, animations, and even practical tools like thumbnails! So let’s dive in and create a captivating image for your scratch project!

What is a Thumbnail?

A thumbnail is a small, miniature version of a larger image or video. It’s like a tiny sneak peek or preview that gives you an idea of what the larger image or video is about. You might have seen thumbnails when browsing videos on YouTube or images in a photo gallery.

Thumbnails are often used on websites, social media platforms, and video-sharing sites to help people quickly understand what the content is about before they decide to click and view the full image or video.

Scratch Programming

Scratch is a visual programming language and an online community developed by the MIT Media Lab. It is designed to teach coding concepts to beginners, especially kids, in a fun and interactive way.

Scratch provides a graphical interface where users can drag and drop blocks of code to create animations, games, stories, and interactive projects. If you are new to scratch programming, then we recommend you read this introductory article on block coding.

Creating a Thumbnail

To create your amazing thumbnails, we’ll use the Scratch editor. Before we jump into creating, let’s plan our thumbnail.

Think about what your project is about and what makes it exciting. Is it a thrilling game with robots battling in space, or a colorful animation with dancing characters? Decide on the main theme and elements you want to include in your thumbnail.

Step 1: Backdrop

Every great thumbnail needs a fantastic background. In Scratch, we can use the Stage as our canvas. Click on the “Stage” icon at the top to open the Stage editor. Choose a backdrop that matches your project’s theme. It could be a starry night, a beautiful landscape, or anything that sets the right mood!

Step 2: Adding Characters and Props

Now, let’s bring our characters and props to life! You can create your sprites (characters) from scratch or choose from the vast library of sprites available in Scratch.

Go to the “Choose a Sprite” button and pick your favorite characters, objects, or animals to include in your thumbnail. Remember, it’s your magical world, and you’re the master storyteller!

Step 3: Adding Text and Title

Every awesome thumbnail needs a title! Click on the “Text” button in the Scratch editor, and you can add text to your thumbnail. Write a catchy title that represents your project. It could be the name of your game, animation, or whatever you want to call your magical creation!

Step 4: Special Effects

Let’s add some magical effects to make your thumbnail sparkle! Use the “Looks” and “Sound” blocks in Scratch to create dazzling animations and sounds. You can make your characters dance, add twinkling stars, or create a cool intro animation. This is your chance to add that extra magic to your thumbnail!

Step 5: Saving Your Thumbnail

You’ve worked hard on your captivating thumbnail, and now it’s time to save it! Click on the “File” menu and choose “Save now” to save your project. Your thumbnail will automatically be saved as part of your Scratch project.
