# How to find out the size of a face

Ok, I downloaded a 3ds model from a videogame and I was asking how to find out the size of a face:

Here the model:

Here the face that I want to find the size:

I barely know how to use the program... sorry :/

Ok, but i have other issue...

This tell me that the face is 120 of tall:

But this box that is way bigger than the other model tell me that is 16 of tall:

So, i know the box is 16 of tall but its imposible that the other thing that is way smaller can be 120, maybe its 0.120 or something, can you explain me that?

Select the object and enter EDIT MODE (Tab). You will find the settings if you scroll down in the right viewport panel. There are various options you can enable concerning mesh display, such as edge length, face area etc.

• I respond your comment down, sorry but i need to show you some pictures and i couldn find it in this menu... – TMB Jan 20 '17 at 14:00
• In 2.80, the icon which reveals this menu is in the top right of the edit area. There is a selection of icons above the axis gizmo and from the right there are various shading icons, then x-ray and then "overlays" where this menu is. – Tomáš Hübelbauer Dec 9 '19 at 18:59

The issue answer is I have a green big cube and red small cube When i go to edit mode i can see the measurement is 2 same with the other cube measurement both have same measurement. It cannot be possible different size cube having similar value. (in object mode) Click the cube Press > Ctrl+A and select scale. Do with the both cube and see that the value have change now. One is 5 and other is 0.4

To extend comment above by @Tomáš Hübelbauer with screenshots.

For latest version of Blender(2.80+), to display edge measurement you need check this checkbox:

If you want use cm permanently (as I am) you should go to "Scene Properties" tab and select Metric then length. See the picture below:

UPD: a bit later I came across this video, explaining this:
