+# Width
+
+The width function. #width #image #docs
+
+Get the width of an [Image](/microbit/reference/image/image) in columns.
+
+### KindScript
+
+```
+export function width(_this: micro_bit.Image) : number
+```
+
+### Parameters
+
+* none
+
+### Returns
+
+* [Number](/microbit/reference/types/number) - the number of columns in a image. This function returns 5 if the image has 1 frame, 10 for 2 frames, 15 for 3 frames and so on. Divide the number of columns by 5 to find out how many frames an image has (see example below).
+
+The following example gets the width of `img` and stores it in the `w` variable:
+
+### ~hide
+
+```
+let img = images.createImage(`
+. . # . . . . . . .
+. # . # . . . # . .
+. . # . . . . . . .
+. # . # . . . # . .
+. . # . . . . . . .
+`)
+```
+
+### ~
+
+```
+let w = img.width()
+```
+
+### Example: show each frame
+
+The following example uses the `width` function with a [for](/microbit/reference/loops/for) loop to show each image frame on the screen:
+
+```
+let img2 = images.createImage(`
+. . # . . . # # # # . # # # .
+. # # . . . . . . # . . . # .
+. . # . . . . . # . . . # . .
+. . # . . . . # . . . . . # .
+. . # . . . # # # # . # # # .
+`)
+for (let i = 0; i < img2.width() / 5; i++) {
+    img2.showImage(i * 5)
+    basic.pause(1000)
+}
+```
