3 5 cm actual size. On-screen pixel ruler in Windows. How to measure in the Tape Measure app on iPhone

Let's start with an English-type ruler. It has 12 divisions (large marks) indicating inches. 12 inches equals 1 foot (30.5 cm). Each inch is divided into 15 divisions (small marks), that is, each inch on the ruler is indicated by 16 marks.

• The higher the mark, the higher the indicator. Starting at the 1" mark and ending at the 1/16" mark, the marks decrease in size as the readings decrease.
• The ruler readings are read from left to right. If you are measuring an object, line up its beginning (or end) with the left end of the ruler. The number you find on the ruler on the right determines the length of the object.

The English type ruler has 12 inch divisions. They are numbered and indicated by the largest marks. For example, if you need to measure the length of a nail, line up the start (or end) with the left end of the ruler. If the end (or beginning) of the nail lines up with the large "5" mark, then the nail is 5 inches long.

• Some rulers also have "1/2" markings on them, so be careful not to confuse the largest inch marks with the smaller ones.

1/2 inch marks. These marks are half the length of the inch marks. They are placed in the middle of each 1-inch division because they represent half an inch. That is, such marks are applied between 0 and 1 inch, 1 and 2 inches, 2 and 3 inches, and so on. There are 24 such marks on a 12-inch ruler.

• For example, line up the left end of the ruler with the top of the eraser on your pencil. If the tip of the lead points between the 4" and 5" marks, then the length of the pencil is 4 and 1/2 inches.

1/4 inch marks. These marks are placed in the middle of the 1/2 inch marks and are smaller in size and indicate 1/4 inch. In the first inch, these marks indicate 1/4, 1/2, 3/4 and 1 inch. Although there are separate "1/2 inch" and "1 inch" marks, they are included in the 1/4 inch measurements because 2/4 inch is equal to half an inch and 4/4 inch is equal to 1 inch. There are 48 such marks on a 12-inch ruler.

• For example, if you measure a carrot and the end lines up with the mark between the "6 1/2" and "7" marks, then the length of the carrot is 6 and 3/4 inches.

1/8 inch marks. These marks are placed between the 1/4 inch marks. Between 0 and 1 inches there are marks indicating 1/8, 1/4 (or 2/8), 3/8, 1/2 (or 4/8), 5/8, 6/8 (or 3/4) , 7/8 and 1 (or 8/8) inches. There are 96 such marks on a 12-inch ruler.

• For example, you measure a piece of fabric and its edge is aligned with the 6 mark after the 4" mark, which is located directly between the 1/4" and 1/2" marks. This means the length of the fabric is 4 and 3/8 inches.

1/16 inch marks. These marks are placed between the 1/8 inch marks. These are the smallest marks on the ruler. Between 0 and 1 inches there are marks indicating 1/16, 2/16 (or 1/8), 3/16, 4/16 (or 1/4), 5/16, 6/16 (or 3/8) , 7/16, 8/16 (or 1/2), 9/16, 10/16 (or 5/8), 11/16, 12/16 (3/4), 13/16, 14/16 ( or 7/8), 15/16, 16/16 (or 1) inches. There are 192 such marks on a 12-inch ruler.

• For example, you measure a flower stem and the end of it lines up with the 11 mark after the "5" mark. In this case, the stem length is 5 and 11/16 inches.
• Not every ruler has 1/16 inch marks. If you plan to measure small objects, or you want to take precise measurements, make sure your ruler has these markings.

How to organize an on-screen pixel ruler in Windows to measure the length and height of windows or other interface elements and adjust them to your size? Such a specific task can be faced not only by designers or developers, but also by ordinary users working with documents or projects of their specialized software. Let's look at three programs below for implementing a screen ruler.

1. SPRuler

SPRuler - a small free utility SPRuler is not intended for anything more than displaying an on-screen pixel line on the Windows screen. It displays two scales: at the top with an interval of 10 pixels, at the bottom – 8 pixels. The scales are swapped in the context menu options. There we can change the orientation from horizontal to vertical, apply light or dark colors to the ruler, and adjust its transparency. It is increased or decreased by simply pulling the edges or specifying a specific value in the options. Copies of the ruler with horizontal and vertical orientation can be launched as desired. There is support for hotkeys.

2.Window Ruler

Window Ruler is another free, minimalistic utility that implements both horizontal and vertical rulers simultaneously in the Windows environment. But not only pixel dimensions, the sizes of objects on the screen can also be measured in points (typographic points), inches, centimeters and millimeters. Increasing and decreasing the ruler is done by pulling the edges. The dimensions of the screen area specified in the ruler window are displayed in the lower right corner of this area. Window Ruler does not provide the ability to manually enter size values, but it does have options for setting five areas with standard screen sizes.

3.FastStone Capture

The screen ruler is part of a functional paid screenshot - the FastStone Capture program. This is an option for complex work on creating screenshots with adjusting Windows interface elements to the required dimensions. For example, for implementation in documents, presentations, other projects of content creation programs, publications on the Internet. The FastStone Capture ruler switches from horizontal to vertical by double-clicking on it; changing its size is done by pulling the edges. There is no option to set dimensions manually, but there is an option to display a small interval of the scale to which the cursor is placed on an enlarged scale. The preset pixel units can be changed to inches or centimeters. The color and transparency of the ruler are customizable. For ease of launch, you can add it to the floating quick access panel to FastStone Capture operations.

Do you need to measure something, but don’t have a ruler at hand? This situation is no longer surprising - after all, finding a smartphone or monitor near you has become much easier than a real ruler, caliper or other tool that measures length :)

Today I will tell you about three services that solve the problem of measuring any object in centimeters better than anyone else. I studied about a couple of dozen online rulers and chose from them only those that give a minimum error of a few millimeters and allow calibration (adjustment of actual dimensions) for the most accurate measurement.

1. Piliapp

This screen ruler is 30 cm long. When you access the site, the service algorithm itself automatically determines the diagonal of your monitor so that the ruler on the screen is displayed in natural size.

Sometimes the algorithm is slightly wrong and gives a measurement error of +/- 5mm. This is why I recommend manually specifying the diagonal if you know it. To do this, click on the green button and in the window that opens, indicate the number of inches of your screen.

There is a much more reliable way to increase the accuracy of the measurement. To do this, click on the “I don’t know my screen size” button and on the page that opens, attach any of your bank cards (they are the same size in all countries of the world) to the template. Move the scale slider until the screen template and your map are the same size.

By performing this kind of calibration, you can be 100% sure that the virtual ruler will exactly match the real one. Link

2. Ruler

This ruler measures dimensions in inches by default, so we need to immediately switch the metric system to the usual centimeters:

In this service, you yourself need to indicate the diagonal of your screen in the appropriate window, selecting it from the list or specifying an arbitrary number, and click the “Calibrate” button.

If you don’t know the exact number, touch the bank card to the screen and select the screen size from the list until the right edge of the card matches the left edge of the corresponding icon on the ruler.

Once you have done this, you can be sure that subsequent measurements will be accurate.

3. Lineykasm

The third online service has all the necessary instructions for making measurements and calibration in Russian.

Therefore, I will only note its main difference from the previous two: you can manually calibrate the screen ruler using not only a credit card, but also such items as:

• Matchbox
• A4 sheet of paper
• Banknote (dollar, ruble, hryvnia)
• CD disk

If it’s relevant to anyone, this service also makes it possible to print the ruler on paper. There are two options to choose from: a standard length of 30 cm and a 12-inch length with fraction markings.

Hello, friends! The online screen ruler is indispensable for many works; in this article we will look at installing the program FS Capture and using its functionality. Using the on-screen ruler is convenient when working with pictures on websites, when creating and revising subscription and sales pages.

Screen ruler of the online editor FS Capture

The blogosphere requires the use of a variety of knowledge and tools to solve various problems. One of these tasks in the blogosphere is measuring various objects on the pages of a blog (site), as well as determining the sizes of various graphic images when replacing pictures in blog templates, preparing subscription and sales pages, adjusting banner sizes and much more.

Since many beginners have not previously encountered the need to carry out such measurements, it is likely that not all of them know about the availability of a special tool for taking measurements on a monitor screen. A tool for measuring on a monitor screen is called a screen ruler, i.e. online screen ruler, we will talk about it in this article, I think this information will be useful for beginners.

So where can you get a screen ruler? First, there are target programs such as VRCP SPRuler, mySize, PixelWindow and others. Secondly, there are graphic editors that have built-in on-screen ruler functions, one such editor is FS Capture.

The graphic editor FS Capture (Fast Stone Capture) is very common among bloggers; it has many useful functions: capturing images from the monitor screen, including scrolling ones, creating screenshots, the ability to apply watermarks, creating various arrows, writing on images, editing and image correction, you can also record presentations and audio.

The FS Capture editor also includes an on-screen ruler. If you don’t have this graphic editor yet, then I advise you to get it, it will serve you well. Old versions of FS Capture can be downloaded for free on the Internet, new versions are paid. Previously I used version 5.3, now I use 6.5.

So, after installing the Fast Stone Capture program, open the image you need, then open the Fast Stone Capture program. To connect the screen ruler, you need to press the far right “Settings” button (see screenshot 1).

In the window that opens, select “Screen ruler”; after clicking on this button, the screen ruler opens.

On the right, with the mouse, we can reduce and increase the length of the ruler (screen 2), and with the help of our hand, the ruler can be moved across the monitor screen. When measuring a graphic object, an enlarged scale is displayed in the upper right or left corner, which allows for very accurate measurements.

To place the ruler vertically, you need to click on one of the arrows (screen 2 highlighted in yellow). You can use the roulette function; to do this, press the double arrow at an angle (screen 3).

If you click the arrow inside the rectangle (screen 4), the settings panel opens with an on-screen ruler. You can choose a horizontal or vertical position of the ruler, you can choose its color and transparency. Here you can also select the unit of measurement - pixels, centimeters and inches.

In this simple way you can measure objects on a blog and in other graphic editors. Of course, it’s up to everyone to decide whether to download a separate program or use the built-in functions of the graphic editor.

If readers are interested, in the future I can prepare an article on the topic of using the Fast Stone Capture graphic editor, online screen ruler, for image editing. Good luck to you
