Hello friends, welcome to Tutorials Point
0:10
In this video we are going to learn Ruler tool in Adobe Photoshop
0:15
So friends Ruler tool in Adobe Photoshop is used to measure distance angles and position coordinates
0:22
in an image. With this tool you can draw a straight line and measure the distance between two points in an image
0:29
So friends the ruler tool is located in a toolbar under the eye dropper tool like here
0:38
Okay, by using a shortcut I you can activate these tools and now you can select a ruler tool
0:46
Now if you want to change from the I dropper tool to ruler tool then you need to press Shift plus I to switch from one tool to another
0:56
So right now I'm just selecting this ruler tool. ruler tool so friends let's see the practical example how you can use this ruler tool and all the
1:05
properties you can see over here fine so first of all I am opening this footage okay so to use
1:13
the ruler tool first of all we need to select the tool and we need to use click from the one
1:20
point and you know need to drop down your mouse click and you need to go to the second point for
1:27
example here and once you release your mouse pointer you can see all the properties
1:32
over here you can see your x your y your width w means with the width with the width of this ruler as well as you can also see height because we didn make a straight ruler that why we also get the height and
1:48
that's why we also get an angle now to create a straight line for that we need
1:55
to press a shift now if you want to clear this ruler you need to press over
2:00
here which is called clear just press clear and the ruler will be clear okay
2:06
So now see one more example I am just measuring from here to here but a straight line for that I am just pressing shift while I am dragging from here to here
2:19
okay so friends as you can see now our x-axis will be this y-axis will be this and width is 919.07 but there is no height because we have a straight line that's why height will be zero and
2:36
angle is also will be the zero now what is this l1 l1 with one ruler right now we just created a one
2:45
ruler that's why the l1 will be this now if you want to create another ruler then you can see the
2:52
value over here so this is for the measuring particular area now friends i'm showing you how
2:59
you can calculate height i'm just clear this and now i'm just calculate height for that i'm
3:06
just selecting this door from here to here by pressing shift you can just make it a
3:15
proper straight line so guys as you can see I can got my height will be 4 4 1 now guys as you can see we are going from the top to down That why our height in positive value
3:30
Now if we are going to down to top and as you can see our height will be in minus
3:36
Same in our horizontal line. If we are going to right to left then our fifth value will be in minus
3:45
Now next we are going to learn how we can calculate. angle okay so where this is very important so first of all I am clearing this
3:55
now to calculate angle first of all we need to create a one ruler like this okay
4:03
and once you release your mouse pointer your one ruler is created now if you
4:08
want to start from here to here to measurement this angle for that you need to
4:14
press alt from your keyboard and once you press alt from your keyboard
4:18
and you move your mouse pointer to this point and as you can see the icon will be changed
4:25
to the angle icon this is for measuring the angle just click here and from here to
4:32
here you can get another ruler so friends as I told you before this is L1 for
4:39
first ruler and L2 for the second ruler and as we can see the angle will be
4:44
89.2 degree so this our angle will be 80. 90 degree So friends using a ruler tool you can measure with height position angle as well as a lot of things in Adobe Photoshop So friends like this we can also find any angle in a real time footage so for now I am just clear this okay now friends sometimes you have some tilted
5:16
layer for example this in this footage our iPhone will be all tilted now if I
5:23
want to make a straight layer for that we have here one option straighten layer so
5:29
for that first of all we are using our ruler tool and then we are just making one
5:36
ruler from here to here fine and now we are going to press straighten layer
5:43
so friends as you can see our layer will be the straighten see so like this
5:53
you can also straighten any layer in Adobe Photoshop so this is a very useful
5:59
option in a ruler tool so this is a straighten the active layer to make the ruler level
6:06
so friends like this you can use a different different example or you can also use a
6:13
real-time footage for a architect work to find a width height as well as angles in
6:19
Adobe Photoshop now here you need to note one thing is that the ruler tool is
6:25
useful when you need to measure distance or angle in an image
6:29
or when you need to draw a straight line with a specific angle so guys that's all
6:36
about ruler tool thank you so much see you in the next video
