Design

Designs are custom-made patterns comprised of 32x32 pixels that can be created in each game (excluding ) through an editing interface. The created design can be applied to clothing, umbrellas, hats, carpeting, and wallpaper. Designs can also be placed as paintings and, from onward, overlaid on the ground. Designs that are placed on the ground will prevent anything from growing or spawning in that tile and, prior to, cause items dropped from trees and fallen balloon presents to disappear if there is not enough space for them to land. In only, players can also place a design on their front door. In and, designs can be used to customize furniture. Befriending Sable in the latter game will unlock a variety of pre-made designs that can be applied to certain furniture.

Sharing
and can generate QR codes to share custom designs. To unlock the feature in, the player must first befriend Sable who will bring in a new sewing machine that will allow them to create and read QR codes. In, the machine is available in the upstairs of Nook's Homes after completing the lesson "Even More Designs" in exchange for 5 Play Coins. QR codes are stored as images on the SD card inserted into the Nintendo 3DS. Normal designs use one QR code, but pro designs are comprised of four separate codes. Once the codes have been scanned, a slot must be selected for the design to be saved to.

is backwards compatible with QR codes created for these previous titles (excluding the Standee design type) via the NookLink service of the Nintendo Switch Online app for iOS and Android. The app can scan the QR codes, saving up to one design at a time and overwriting any previously scanned design. The player must then select the Download function of the Custom Designs NookPhone app to import the design from the app into the game itself. Despite utilising a new and different format for pro designs, imported designs retain the format used in the previous titles.

Designs that are created in can be shared after befriending Sable once again. In this game, shared designs do not use QR codes. Instead they are uploaded to Nintendo's servers and can be shared with other players by having them input an alphanumeric code. A Nintendo Switch Online subscription is required for this service.

In all games, imported designs cannot be modified. The metadata for each design contains the author's name, their town name, and a hidden identifier. Should this metadata somehow match that of another player, the game will treat the design as if it is their own and allow them to modify it.

e-Reader designs
These designs are available as part of the Animal Crossing-e series. Scanning a design card will show the corresponding design on the Game Boy Advance alongside Sable's comment. If the game is linked to the e-reader, the design will be added to the game.
