Sticker Pack Guide

To submit a sticker package to mit messenger you need to provide:

1. An avatar.
2. A banner.
3. A preview.
4. The stickers themselves in three sizes for iOS and five sizes for Android.

Image files are in png format and 72 ppi.

Banner

The Banner will be placed at the header of your sticker pack in the Sticker Store.

Avatar

The sticker pack avatar is placed on top of the sticker package as the “face” of the sticker collection.

It is visible in Sticker Store and aims to highlight the signature sticker of the package.

Preview

The sticker preview gives the chance to explore the entire package for the users to decide whether they want to add the package or not. When clicking on the “Avatar” a popup screen appears allowing the users to see what their chosen package includes. It creates the general impression of the package, so the order of the stickers matters a lot in this case.

Stickers

When creating the package remember to align the style, the font and the colors of the stickers. We advise using 2-3 major colors and keeping all fonts consistent.

Sticker Size

When deciding the sizes of the sticker, remember to check how it will look on a real device. You can do that by inserting the sticker on a screen shot to test how it looks. Remember that mit messenger users can change the background color on their chats. So test it out with various background themes.

Once the stickers are ready, place them in the grid with your preferred order. Even if the sticker occupies only 1 cell of the grid, this sticker’s file size (that will be displayed inside the chat) should be as big as the ones that occupy several cells of the grid.

Preview Sticker Pack with Grid

Once all the stickers are ready, those should be placed inside the grid for the the preview of the full package.

The grid consists of blocks and each block includes 16 cells.

See below for the required file width and length. it also depends on the number of stickers. Blocks can be added, however, remember that the number of blocks should be an even number.

The given file width, length depends on the number of stickers.

Sequence of Stickers

The names of the sticker files are saved in a specific order (for example, 2011_1000). The first digit (2011) is the package number.

The second number is the order of the stickers from left to right (1000, 1001, etc.).

*Please save the stickers in the correct sequence and in the same folders as in our example.

Tips for Great Selling Stickers

Provide a lot of variety, whilst sticking to the theme of your sticker pack. Use stickers that express daily activities, moods, and emotions.

Avoid stickers that are difficult to use in daily conversation, such as objects and scenery.

Avoid stickers that have poor visibility, such as pictures that are too long or full-length illustrations of tall characters.
