Screen rulers. How to measure the size of any object? On-screen pixel ruler in Windows Ruler on top of all windows

Not long ago I had to review one program in the description of which it was necessary to indicate the exact length and width of the toolbar. As you understand, there could be no talk of determining the dimensions “by eye”; the length and width had to be indicated precisely and not in centimeters and millimeters, but in pixels.

Arigato Ruler

Then I decided to try another free ruler - Arigato Ruler. Unlike Screen Ruler, it has a clearer division scale and, in addition, a customizable screen magnifier. And besides, you can use it to measure color and determine the exact position of the mouse cursor in space. Supports transparency, reflection, changing background, changing position, copying color value.

You can move Arigato Ruler around the screen using either the mouse or the arrows (the latter gives high accuracy). By the way, it is also portable.

Universal Desktop Ruler

If this is not enough for you, I can offer another tool, although this time it’s paid - Universal Desktop Ruler - a universal screen ruler.

With its help, you can measure not only the width and height of an object, but also the area and perimeter. In addition, Universal Desktop Ruler can measure angles, the length of inclined lines, count the number of objects on the screen, and also save the history of previously made measurements in a log. Download Universal Desktop Ruler 3.6:

Utility useful for web designers, programmers, photographers, artists, those who deal with digital images(pictures, photographs, icons, etc.). Program SPRuler is an electronic ruler for measuring distances and sizes of objects on a monitor screen in pixels. The program is free, convenient, minimizes to the system tray, supports Russian and English languages.

Program ruler

Electronic ruler(or digital ruler, if you can call it that) looks like the real thing, the design provides light and dark shades of the instrument with a scale dividing line and transparency settings. The ruler moves across the screen very smoothly. The ruler displays two types of scales at intervals of 10 and 8 pixels. It is possible to clone an already running line and place SPRuler on top of all windows. When you start the program, the length of the ruler is adjusted automatically depending on the screen resolution (maximum up to 2048 pixels). The tool quickly rotates to horizontal and vertical positions. SPRuler supports the function automatic start at start operating system.

SPRuler Installation Note:

If you are installing SPRuler on Windows NT/2000/XP/2003/Vista/2008/x7, run the program installation distribution as Administrator.

In the process of optimizing some website elements, it is very important to maintain proportionality, otherwise the web project will turn into a pathetic, unattractive sight. It's one thing when a person designs on a piece of paper. In this case, you can use a pencil and ruler. Completely different circumstances arise if actions must be performed within the monitor. In such circumstances, you need to use the free mySize program.

mySize screen ruler is an excellent, extremely easy-to-use tool designed to measure the length and width of elements displayed on a computer screen.

Under what circumstances might an on-screen ruler be useful?

Working with graphic elements (editing images in accordance with the required parameters).

Editing the site (measuring the parameters of the site header, sidebar, associated with the need to make changes to the design of the resource).

The mySize line is a first-class assistant, which was previously sorely lacking for all webmasters and web developers. The program implements 3 measuring modes:

In pixels.

In centimeters.

In inches.

mySize – installation features

The installation of this software is no different and is performed in the standard Windows sequence. We launch the installer, after which a window will pop up welcoming the installation wizard. Click the “Next” button, read the license agreement, accept the terms (the “Accept” button) and click “Next” again. Select the installation folder – Next. We wait 20 seconds, after which a shortcut like this will appear on the desktop.

Well, the screen ruler is installed.

To open the program, double-click the left mouse button on the shortcut. The tool has the following design.

mySize screen ruler - subtleties of operation

As you can see, this is an ordinary double-sided ruler, with not quite ordinary possibilities. In order to call the system menu, click the left mouse button in the area where the two rulers join (1).

You can move the on-screen ruler by holding down the mouse. If you need to perform a minimal shift, use the special arrows located near the menu (2).

The free value is changed by sliders located at the end of the horizontal and vertical ruler (3).

The need for slight movement of the ruler is carried out using the buttons for moving the sliders (4).

mySize - ruler settings

Hide – a tab that hides the program. After clicking, the program shortcut is displayed in the tray.

Measurement – ​​specifying parameters in pixels, centimeters or inches.

As mentioned in passing, this is not an ordinary ruler, providing the opportunity not only to measure an object, but also to take a screenshot of it. To do this, click on hotkey"S".

This will call up additional elements in the form of two red lines forming a rectangular area.

Rulers – select a horizontal or vertical ruler.

Often there is a need to measure something on your monitor screen. This need most often arises when working with pictures. When you need to print something, and you are not sure that the result on paper will be the same as you expected. For example, I used to use an ordinary sheet of checkered paper, fit it to the screen and thus find out the size of a picture or something else.

It’s not that I’m such a dummy, I just didn’t have such an urgent need for ruler programs. But for those who work a lot with graphics, printers, or just need to measure something, I have prepared a description of several rulers and links to pages where they can be downloaded.

Metric ruler

The JR Screen Ruler is the only ruler I could find with a centimeter unit. But in addition to centimeters, you can also measure in pixels, inches and picas.

Works in all windows Windows applications, just drag the mouse where you need it. It is possible to flip the ruler into a vertical and horizontal position.

The disadvantages of this program include the inability to change its color and the need to customize it. Without adjustment, there is a possibility of large measurement errors.

It’s very easy to set up; select the unit of measurement you need, say centimeter.

Apply a regular plastic ruler to the monitor screen (to the virtual ruler) and compare how much the scale readings diverge.

If everything matches, then the setting can be skipped. If there is still a discrepancy, then you need to change the number of pixels per unit of measurement. To do this, right-click on the ruler and select - Pixels per inch. And in the Input Box, change the pixel values ​​until centimeters become centimeters. For example, my value was 105.

You can download the program from the official website. The size is less than 500 KB, does not require installation, you can get started right away.

Browser ruler

I can recommend a couple of cool rulers for those who use a browser Google Chrome

Ruul. Screen ruler - beautiful pixel rulers, you can use several at once on one page. As you already understand, we are talking about expansion. Rather suitable for a developer, because... You can only work with them in a browser. There is even a special reminder showing what letters of different sizes look like in pixels. There is one drawback - this extension does not work on all pages, for example, on the Google website.

And the last one, my favorite - Ruler Opera Widget. Nothing special at first glance, but for some reason I really like this widget. Unfortunately, only the pixel scale, but works in all Windows windows. Be it a browser, notepad, desktop or any folder.

For some reason it was removed from the Opera Add-on, where you can download it in Yandex or Google.

Web designers often need to determine the size of some object on the screen. And it is not always enough to look at the properties of an object. In such situations, special utilities come to the rescue that allow you to measure elements in any part of the screen. mySize is one of these programs.

The first thing that captivates you about this free program– this is simplicity and convenience. No unnecessary actions, unnecessary buttons and settings. When inactive, it becomes translucent so that it does not block other windows. All we see at launch is a line.

Moreover, it does not need to be applied to measure. Instead, we stretch it horizontally or vertically, immediately determining the size. Positioning the edges of the ruler is very simple - just move the cursor to the edge and, holding down the left mouse button, move it.

Small buttons at the edges of the ruler are designed to accurately stretch the ruler by 1 pixel.

You can move the entire ruler around the screen, just like any window. For more precise movement, you can click the arrows in the corner of the ruler. An alternative option is using control keys.

The size is always shown on the ruler.

mySize has another useful feature called screener. Its essence is that you can simultaneously stretch both rulers by moving this same screener. It is displayed strictly at the intersection of the lines and is indicated with a red marker. You can turn it on by pressing the key S or through the menu. It is very convenient to adjust the ruler to the object on the screen using a screener.

The program has a menu, you can call it by clicking in the corner of the ruler.

Through the mySize menu you can configure several more ruler parameters.

Measurement– allows you to select the unit of measurement displayed when working with the ruler. Our choice is pixels, centimeters or inches.

Settings– includes three points:
Show on top of all windows– enabling this option allows the ruler to always remain visible;
Show on taskbar– to display the program button in the taskbar, since by default it is displayed only in the system tray;
Screener– enable the previously discussed screener.

Rulers– contains two items designed to enable/disable horizontal or vertical rulers. By default, both rulers are displayed at once.

Moving– this menu property allows you to configure strict movement of the ruler along only one of the axes - X or Y. By default, mySize moves along both axes. Okay, holding left Shift and by moving the cursor, you can only move the ruler horizontally. Same with left Ctrl You can achieve a ruler offset strictly vertically.

Hide– selecting this item in the menu causes the ruler to collapse into the tray. To return the mySize ruler to the screen, just double-click on the program icon in the tray.

Finally, let's talk about one more useful function utilities – the ability to take a screenshot. It appears only when the screener is turned on - an item appears in the menu Take image. For those who like to do everything using the keyboard, the key will help C . Everything that ends up between the rulers and guides of the screener can be saved to a file.

In a separate window Preview we will see a screenshot and a button [Save]. mySize saves the screenshot in JPG, BMP or PNG format.
