When describing a bag, width typically comes before height. The standard convention is to list dimensions in the order of width, height, and depth (or length), often abbreviated as W x H x D. This helps provide a clear and consistent understanding of the bag's size.
width always comes first
width
I assume You mean, Which Comes first Height or Width? Typically when speaking its Width First then Height. Example: When someone is describing the resolution of the Computer monitor they may say I have my resolution set at 640 by 480 (640 x 480) This refers to the WIDTH x HEIGHT of the pixels in the resolution (640 Pixels Horizontally/WIDTH & 480 Pixels Vertically/HEIGHT)
it is lxwxh (width x hight)
You can do it whichever way is more convenient for you. The answer is the same either way.
They can come in any order.
Ignore the pendants and assume no conventions..always state clearly your dimensions with unit used (cms or ins.) and orientation i.e. either WxH or HxW or Portrait or Landscape. This way no confusion.. it doesn't take much to be clear but can save a lot of trouble.
When defining a card size, width typically comes first, followed by height. This convention is standard in various design specifications, including business cards and playing cards. For example, a card size might be described as 3.5 inches wide by 2 inches high, emphasizing the width before the height.
Width by height.A standard sheet of typing or copy paper is 8-1/2" by 11"....eight and one half inches wide and eleven inches high. A sheet of legal paper is 8-1/2" by 14".The world standard of DIN A 4 paper is:Width = 21.0 centimeters by height = 29.7 centimeters.
When measuring a picture, the width typically comes first, followed by the height. This convention applies to both photography and artwork, where dimensions are usually listed as "width x height." For example, a standard frame might be described as 24 inches wide by 36 inches high. This format allows for a clear understanding of the picture's orientation and size.

When measuring an object, the order of length, width, and height can depend on the context and the specific object being measured. Generally, length is measured first, followed by width, and then height, especially in rectangular objects. This order helps establish a consistent approach, but ultimately, the priority of measurement can vary based on the application or convention used.
