I am making a game and have a problem with UI. I made it to scale with the screen size. In 16:9 it looks as I want to:
UI is where I want it to be.
But when I switch to 2160 x 1080 I have a problem.
My UI is outside my game screen
I want that my UI on 18:9 stays in the same position as in 16:9. Any solutions to make it stay inside game bounds?
Canvas object -> Canvas Scaler component:
Scale With Screen Size
Match = 0 (0 for vertical app, 1 for landscape)
And then you need to change anchors for ui objects to align not from borders, but from center.
If you want UI to cover entire page make sure you hold shif + alt and select the stretch preset Unity will always cover the entire screen irrespective to resolution

Unity's UI screen is different from the in-game world space.
For the UI part you can easily fix the issue of the size and position by considering the following:
First thing you need to check is the Canvas Scaler component which is automaticaly generated on your Canvas gameobject.
Canvas Scaler Example
First under The UI Scale Mode you should choose the "Scale with Screen Size" which will make UI elements bigger the bigger the screen is.
Second is the Reference Resolution which is the resolution the UI layout is designed for. If the screen resolution is larger, the UI will be scaled up, and if it's smaller, the UI will be scaled down. A good example is to set the dimensions int something like this (1920x1080) which is the most common landscape resolution.
Third is the Screen Match Mode which is a mode used to scale the canvas area if the aspect ratio of the current resolution doesn't fit the reference resolution. With other words if you change your in-game resolution this will handle your UI elements.
Fourth is Match which will determine if the scaling is using the width or height as reference, or a mix in between. So if your game is in landscape mode you should set it to 0, if it's in portrait mode you should set it to 1.
Last thing to keep in mind that will affect your UI elements position is the Anchor presets which is part of the Rect Transform component on each of your UI elements.
I want my Unity 2d game responsive in all android mobile device. So i anchor 4 canvas to 4 edge (top left, top right, bottom left, bottom right).
But when i change a device, the size of each component is not change. Now i want the size of each component change depend on each resolution of device. What should i do or what tutorial i can follow.
Problem will come when i get small screensize, it like this
Canvas Scaler
You can solve it using Canvas Scaler.
You can find various options in the list in UI Scale Mode.
When selecting the option to fit the commonly used screen size,
If you want to align UI elements to the height, set Match, an element of Screen Math Mode, to Height, and if you want both height and width to match, place it in the center.
I can not change canvas' size when it's in Screen Space - Overlay Mode; After some research I found that the size of a canvas is determined by your game's screen size. The canvas just covers your screen. So I think I could change my camera's size to change canvas' size. But it does not work. Does anyone know how to set a specific size to a canvas?
So may be my question should be how to change the screen size showed
in editor?
To change the screen size, go to the Game window (accessed by the menu "Window->General->Game"). At the top of the window will be a screen size menu (outlined in green, below) to change the screen size. When pressed, it will display the list of screen sizes that will be emulated. I say "emulated" instead of "displayed" because it is possible to have a screen size larger than the screen on which you are working. It is also possible to zoom into a screen. The "Scale" slider (to the right of the screen size menu) will allow you to scale up/down.
As a note, the list of screens and resolutions shown are related to the current build target (accessed by "File->Build Settings..."). For example, common iOS screen sizes are displayed in the list when the build target is iOS.
Use the Canvas Scaler Component
Unity3D Documentation: Canvas Scaler
I have created a 2D game with an orthogonal camera and using 16:9 display size.
I dragged my background image onto the hierarchy (it's about 2048x1152) and then set the camera size to be 22.5, which made it fit the background perfectly and displays just right.
However, when I add a Canvas for a UI it is absolutely giant, about 100 times bigger. It only becomes 'normal' size with respect everything else added when I set the camera to its default size of 5. So when I add a small graphic, it too becomes giant.
I'm simply following a book I read and I'm not doing anything to deviate.
Am I doing something wrong? Below is what I mean. The background image is the little image in the bottom right and the outlined rectangle is the canvas with a small graphic added.
Thanks.
To force your Hierarchy Canvas UI to the same resolution as the Camera View in your Unity Editor Scene window resolution (i.e. not ridiculously massive), or in other words get the Canvas to fit into the Camera size in the Scene, do the following:
Set the Canvas component's Render Mode to Screen Space - Camera.
Make sure you select or drag the relevant Camera from the Hierarchy to the Render Camera field in the Inspector.
You should use the Unity canvas for this along with the canvas scaler component. If I'm not mistaken it will scale all elements relative to the screen they are viewed on.
The canvas scaler allows you to match the scaling based on a preferred viewport size which is a life saver.
However this may not fit you needs perfectly as it would mean that the background element would become fixed. So if you wanted to pan the element you would need to move it's x and y elements within the canvas.
Hope that helps?
I have a 2D game set to 1080p pixel size (so each unit equals 1 pixel) and I have added a canvas to my scene. However the canvas fills only about 1/8th of the screen and is also not central either. All the canvas size and position settings are locked so I cant move it or resize it. The canvas itself does reflect the screen (ie if I put text in the top right corner it appears correctly) but the size makes it hard to judge where best to position the elements).
How do I get the canvas to fill my scene?
On your canvas, set the Canvas Scaler component's Ui Scale Mode to Scale with Screen Size. Then you can define a Reference Resolution of 1080p, i.e. 1920 x 1080.
EDIT: To see the canvas fit into the camera's size in the scene, change the Canvas component's Render Mode to Screen Space - Camera, and drag the camera from the hierarchy to it.
