What does sp mean in font size?
SP: is an abbreviation for Scale independent pixels. It is the same as the dp unit, but it is additionally scaled according to the user's font size selection.
> Scaleable Pixels OR scale-independent pixels - this is like the dp unit, but it is also scaled by the user's font size preference. It is recommended you use this unit when specifying font sizes, so they will be adjusted for both the screen density and the user's preference.
So, when should you use sp and when you should you use dp? Use sp for text size… because but it is scaled by the user's font size preference. Use dp for everything else.
Scalable pixels (sp) serve the same function as density-independent pixels (dp), but for fonts. The default value of an sp is the same as the default value for a dp. The primary difference between an sp and a dp is that sp's preserve a user's font settings.
When defining text sizes, however, you should instead use scalable pixels (sp) as your units (but never use sp for layout sizes). The sp unit is the same size as dp, by default, but it resizes based on the user's preferred text size.

It stands for density-independent pixel. It is also sometimes denoted as dip. | It stands for scale independent pixel. |
designations refer to? The "sp." is an abbreviation for species. It is used when the actual species name cannot or need not or is not specified. The plural form of this abbreviation is "spp." and indicates "several species. Example: Chrysoperla sp.
SP stands for Sponsored Post and means a social media post has been paid for by an advertiser. Using #SP Social Media is supposed to inform a user's followers that the post is in fact advertising, although the effectiveness of this is disputed.

As dp is a physical unit it has an absolute value which can be measured in traditional units, e.g. for Android devices 1 dp equals 1/160 of inch or 0.15875 mm.
What is dp and SP sockets?
The significant difference between an SP switch and a DP switch is that the latter has four brass terminals instead of two, with an additional ground terminal usually not found in SP switches. The two terminals make it possible to connect two pairs of wires from a 240-volt circuit.
What's the conversion of pixel and dip? In Android, we have a baseline density of 160 dots-per-inch(dpi). So, for a 160 dpi screen, we have 1 pixel = 1 dp and 320 dpi screen, we have 2 pixels = 1 dp which is 2x.

A pixel (px) at 96DPI (dots per inch) is equal to 0.2645835 millimeters, 0.010416675 inches, or 0.75 point. It is a measurement of how tall a font is in pixels which are visible on your computer screen.
The nuance here is that 160 dp (or dip ) is roughly 1 inch, while 72 pt is exactly 1 inch. The difference is how android converts both units to pixels, which depends on the screen density of the device. A single dp is a single px on a device at 160 dpi.
Device | Pixel Size | Viewport |
---|---|---|
LG G5 | 1440 x 2560 | 480 x 853 |
One Plus 3 | 1080 x 1920 | 480 x 853 |
Samsung Galaxy S9+ | 1440 x 2960 | 360 x 740 |
Samsung Galaxy S9 | 1440 x 2960 | 360 x 740 |
The most generic full form of the acronym DP is used in terms of social media as a display picture. It is also known as a profile picture or wallpaper. A display picture is an image that one puts in their social media handles such as Instagram, Facebook, and WhatsApp.
It is often formatted as width x height or pixels per inch. Because pixels aren't always the same size, it is possible to have two devices with the same screen size and different resolutions. The higher the resolution, the higher the image quality and more detail included in the image.
You can take either the horizontal or vertical resolution. Once you have the resolution, you must measure the length of the display. Usually, this will be measured in inches (2.54cm = 1 inch). If you divide the two numbers, you'll find the “pixels per inch” (ppi).
Density-independent pixels (dp)
Density-independent pixels (pronounced “dips”) are flexible units that scale to uniform dimensions on any screen. When developing an Android application, use dp to display elements uniformly on screens with different densities.
The most popular phrase that this acronym stands for is “display picture.” It is another way to refer to someone's profile picture on social media sites.
What is dp in CSS?
A dp is equal to one physical pixel on a screen with a density of 160. To calculate dp: dp = (width in pixels * 160) / screen density. When writing CSS, use px wherever dp or sp is stated. Dp only needs to be used in developing for Android.
The em is simply the font size. In an element with a 2in font, 1em thus means 2in. Expressing sizes, such as margins and paddings, in em means they are related to the font size, and if the user has a big font (e.g., on a big screen) or a small font (e.g., on a handheld device), the sizes will be in proportion.
So, by default 1em = 16px, and 2em = 32px.
A pt is 1/72th of an inch and is a useless measure for anything that is rendered on a device which doesn't calculate the DPI correctly. This makes it a reasonable choice for printing and a dreadful choice for use on screen. A px is a pixel, which will map on to a screen pixel in most cases.
What is a Pixel (px)? A pixel (px) at 96DPI (dots per inch) is equal to 0.2645835 millimeters, 0.010416675 inches, or 0.75 point. It is a measurement of how tall a font is in pixels which are visible on your computer screen.
An em is a unit of measurement, relative to the size of the font; therefore, in a typeface set at a font-size of 16px, one em is 16px. The em square is the “box” that each glyph is sized relative to. So, at 12 points, the em square is 12 points wide.
EM is relative to the current font size of the element (2em means 2 times the size of the current font). So, If the font size of body is 16 pixels, then 150% will be 24 pixels (1.5 * 16), and 2em will be 32 pixels (16 * 2).
2. When referring to HTML, the <em> tag (short for emphasized) is used to give emphasis to a certain block of text. Emphasized text is often displayed in italics, like this.
If a font-size has not been set on any of the <p> 's ancestors, then 1em will equal the default browser font-size , which is usually 16px . So, by default 1em is equivalent to 16px , and 2em is equivalent to 32px .
Ex: The value of “1vh” will be 10 pixels (px), and the value of “10vh” will be 100px if the viewport is 1200px wide and 1000px high.
Should I use em or px?
PX units ensure consistent results even if that's not ideal. EM is relative to the parent element's font size, so if you wish to scale the element's size based on its parent's size, use EM.
- 1inch = 96px. 1inch = 72pt. So given these equivalent values, we can say that:
- 96px = 72pt. In other words:
- 1px = 72pt / 96. Given that 1px = 72pt / 96, the formula for converting px to pt is this:
- pt = px * ( 72pt / 96 )
...
Body Font Size.
px | em | percent |
---|---|---|
13px | 0.8125em | 81.25% |
14px | 0.8750em | 87.50% |
15px | 0.9375em | 93.75% |
16px | 1.0000em | 100.00% |
What is a percent (%)? Percents are also scalable like ems. However, 100% is equal to the current font size. Think of it this way: 1.5em is 1.5 times larger, and 150% is 150 percent of the font size.
Point size measures from the height of the highest ascender (peak) to the baseline of the lowercase x. It then measures from the lowest descender (valley) of the font to the top of the lowercase x. Standardized fonts (e.g. Arial, Times New Roman, Calibri, etc.)
Pixel density
Now, the resolution is expressed in dpi (or ppi), which is the acronym for dots (or pixels) per inch. So, if you see 72 dpi it means that the image will have 72 pixels per inch; if you see 300 dpi means 300 pixels per inch, and so on. The final size of your image depends on the resolution that you choose.
2em means 2 times the size of the current font. E.g., if an element is displayed with a font of 12 pt, then '2em' is 24 pt. The 'em' is a very useful unit in CSS, since it can adapt automatically to the font that the reader uses ... The font-size is set at 1em and the line-height is set to 1.125.
