Here are some Frequently Asked Questions (FAQs) about Scratch.

General Questions

What is the purpose of Scratch?

Scratch is a block-based programming language designed to be easy to use. Scratch is designed for those who are between the ages of 8 to 16 years old, but anyone can use it. Scratch is often used as a beginning language to teach people to code. After knowing how to use Scratch they can start learning other programming languages with a bit more experience. Learn more »

Why should I use Scratch?

Many people consider Scratch easy to use[1] because programming is done by dragging blocks rather than by typing, making it easy for one to learn fundemental coding skills. There is also no way to make a "syntax error". Scratch cannot be used to access computer files, does not provide first class lists, etc. but projects can be shared with the large online community. Learn more »

Where is Scratch made?

Scratch is made at the Scratch Foundation by the Scratch Team, but was created at Massachusetts Institute of Technology (MIT), both of them in Boston, Massachusetts.

What license are Scratch projects under?

Scratch projects uploaded and shared at the website are licensed under the Creative Commons Attribution-Share Alike License 2.0 (CC BY-SA 2.0). If a project is never uploaded to the website, the creator can put whatever license they want on it. Learn more »

Can I sell my Scratch projects?

It is possible to sell Scratch projects, as long as they are not shared on the Scratch Website. The creator can attach any license they wish to the code. However, once a project is shared, it is automatically released under the Creative Commons CC-BY-SA 2.0 license, which allows anyone else to view or remix it free of charge. This means that you will need to have never shared your project to Scratch if you are planning on selling your project, since the Creative Commons License can never be canceled. Selling copies of the Scratch program itself is not allowed.[citation needed] Learn more »

Community Guidelines Questions

How do I report inappropriate content?

To report an inappropriate project, click the "Report this" link below the project. When reporting a comment, a link will be below the comment. For a forum post, click the Report link beneath the post. For a user, the report button is below the "What I've Been Doing" section of their user page. For a studio, the report button is underneath the thumbnail.

What does the Scratch Team do if they find something inappropriate?

In all cases, the inappropriate material is removed and an alert is sent to the user that had posted the inappropriate content. If the account has recently posted other inappropriate content, they get banned. The amount of time depends on how many offenses they have committed in the past. Creating alternate accounts to get around the ban is not allowed, and those accounts will be banned. Learn more »

What do I do about someone who is copying my projects?

Scratch supports remixing, taking a project and modifying it. If someone copies your project (or anyone else's) and doesn't change anything at all, it is OK to report it, making sure to mention that it is an exact copy and posting a link to the original project. Learn more »

What do I do if I see a Scratcher violating the Community Guidelines?

Scratch Program Questions

What is the current version of Scratch?

Scratch 3.0 is the current version of Scratch.[2] The current version of the Offline Editor is 3.29.1, which is released on February 27, 2022.[3] Learn more »

What are the system requirements for Scratch?

Running Scratch 3.0's online editor requires a relatively new web browser: Chrome or Mobile Chrome 63 or higher, Edge 15 or higher, Firefox 57 or higher, Safari or Mobile Safari 11 or higher. Internet Explorer is not supported.[4]
Learn more »

How do I create a new project?

To make a new project while a Scratch page other than the editor is open, click "Create" at the top of the website navigation bar. This will make a blank project with an "Untitled-(# here) title and the default Scratch Cat sprite. From there, the project can be designed in the Scratch 3.0 Online Editor. In the offline editor, access File > New project to create a new project. Learn more »

How do I create a new sprite?

Sprites can be created by uploading an image, by drawing with the Paint Editor, by choosing from the sprite library, or by selecting a sprite at random. These options are available at the bottom of the stage on the button labeled "Choose a Sprite". Learn more »

Is there an eraser in Vector Mode?

Yes, in the Scratch 3.0 vector editor there is an eraser. It is similar to the bitmap eraser but does not work exactly the same way. Learn more »

How do I put things in my backpack?

To put a sprite, script, sound, costume, or backdrop into the backpack, you can drag them into the backpack area when the backpack is opened. Remember that the offline editor does not have a backpack yet, so one will have to do it online. Learn more »

How do I organize my project's scripts?

After you have created your scripts in the editor, right-click the background and select "Clean up Blocks". Your scripts should be automatically stacked in a single column.

However, this may not be the best way to organize scripts, as it can be useful to view multiple scripts side-by-side. To do this, you can move scripts around the editor by dragging the top block of each script. Learn more »

What sound formats can I import into Scratch?

Scratch can import WAV files and some MP3s. Other sound formats cannot be imported directly, but can be converted.[5] Learn more »

Can Scratch's project resolution be changed?

No, it cannot be changed. However, the project can be shown in a larger space using full screen mode. When using vector graphics, this will not reduce the quality or cause pixelation, but raster or bitmap graphics will pixelate and become blocky. The Scratch Team was also considering a 16:9 option for Scratch 3.0; however, this was not implemented.[6] Learn more »

Is there a file size limit for a project?

In Scratch 3.0, projects on the Scratch website can only be shared if each individual asset does not exceed 10 MB and the project JSON does not exceed 5 MB. If a message appears saying that the project is too large, it may be helpful to try to compress or remove long sounds, like music. Also, if the project is in Scratch 1.4 or Scratch 2.0, the project can be opened in Scratch 3.0 and uploaded from there. Learn more »

How do I get help about a block?

The best way to get information about a block is by using the Scratch Wiki. Scratch Wiki articles can easily be found on search engines or the search bar in the Scratch Wiki (at the top right). A list of blocks can be found here. Learn more »

Why don't my projects work correctly online?

Archive.png This article or section documents something not included in the current version of Scratch (3.0). It is only useful from a historical perspective.

Scratch 3.0's Online Editor and Offline Editor use the same HTML/JavaScript player, so projects should run the same online and offline.

In Scratch 2.0, the online editor used the Flash Player. This player was a completely different application from the Scratch 2.0 Online Editor. They sometimes behave a bit differently from the Scratch Program, which might cause problems for some projects. Learn more »

What is Scratch made with?

How do I stop variables from resetting to their default positions?

Archive.png This article or section documents something not included in the current version of Scratch (3.0). It is only useful from a historical perspective.

In Scratch 1.x, variables that are hidden when the project is shared lose their locations. The cure is to make sure that all variables are visible and in the correct location when the project is shared, then have a green flag script hide the ones that need to be hidden when the project starts up. Learn more »

Why does my sprite appear upside-down when rotating?

Due to the default rotation style, sprites rotating will appear upside-down. You can change the rotation style of a sprite by selecting it and using the buttons that appear when clicking on the direction input in the header of the Sprite Pane.

Scratch Modification Questions

What license is the Scratch source code under?

The Scratch Source Code is available under two licenses: the GPL v2, and the Scratch Source Code License.

What is a Scratch Modification?

Document stub.png This article is a stub. It may be incomplete, unfinished, or have missing parts/sections. If the article can be expanded, please do so! There may be suggestions on its talk page. (July 2021)
For a list of modifications, see List of Scratch Modifications. For other uses, see Mod (disambiguation).

A Scratch modification, alternatively known as a mod, is a modified version of the Scratch program, usually made by Scratchers with more advanced knowledge. The most common purpose behind making Scratch modifications is the addition of new features or blocks. Others include customizing the editor, removing limits such as clone limit and improving project performance. Projects made with mods that include extra features or blocks are not supported by the original Scratch program or online players, and the Scratch Website does not allow sharing of such projects.[15] The license for Scratch 1.x source code did not allow the word "Scratch" to be used to refer to modifications, with the exception of attribution to Scratch.

Mod Share

Main article: Mod Share

Mod Share is a website where Scratch 1.x and Scratch 2.0 modifications and projects made in them can be shared and played online.

Scratch Modifications Forum

Various Scratchers wish for a Scratch modification forum, specific to the topic of Scratch Modifications, complaining that the Advanced Topics forum is overflowing with modification information.[16][outdated]
