The Redmi 13C came out in 2023 with a 6.74-inch screen of 720 × 1600 pixels: a 20:9 aspect ratio at 260 pixels per inch. It is an HD+ screen, so a 720-pixel-wide image is all it can show: a larger wallpaper adds file size, not detail.
The Redmi 15C and Galaxy A06 use the same 720 × 1600 resolution, so one wallpaper fits them all.

Both screens show the wallpaper at the same size, but different things sit on top of it.
Menu names change a little between software versions. If an option isn't there, open the picture in your gallery app and look for Set as wallpaper in its menu.
720 × 1600 pixels, the native resolution of its 6.74-inch screen. Use the same size for the lock screen and the home screen.
20:9. The screen is 720 pixels wide and 1600 pixels tall, so an image with a different shape is cropped at the edges when you set it.
Yes. A 4K portrait image (2160 × 3840) has more pixels than the Redmi 13C shows, so it stays sharp, but its 16:9 shape doesn't match the 20:9 screen, so part of it is cropped. Fit it to 720 × 1600 first to choose what stays.
Usually the image is smaller than 720 × 1600 or a different shape, so the phone enlarges it to fill the screen. Make it at the exact size with the tool on this page, and start from the original photo, not a screenshot or a copy sent through a chat app.
Usually not. Most launchers keep the wallpaper still, so 720 × 1600 fills it exactly. If yours slides the wallpaper as you swipe between pages, use 1440 × 1600 instead.
