A coordinate tattoo usually marks a specific place with a few short numbers: where a child was born, the city where you grew up, or the exact spot where you proposed to someone. Before settling on a final design, three choices matter more than the font or letter size: which coordinate format to use, how many decimal places to keep so the location remains recognizable without the text becoming illegible on the skin, and whether to add a graphic element next to the numbers, such as a compass.
- Decimal and DMS (degrees-minutes-seconds) formats describe exactly the same point on a map; choosing between them is about how long you want the text to be, not how precise the location is.
- Four decimal places are generally enough for a location to remain identifiable on the ground; a fifth decimal place rarely adds anything useful for a tattoo.
- You can find the correct coordinates in a few seconds using Google Maps, on a computer or phone, before sending them to your tattoo artist.
What a coordinate tattoo actually means
Unlike a general symbol—a heart, an anchor, or a map outline without numbers—coordinates mark a specific place, not a vague area or an idea. That is why they are most often chosen for moments tied to a precise physical location: the spot where someone proposed, the address of the childhood home, the hospital where a child was born, or the place of a first date. They are usually written as plain text, with numbers and direction letters (N, S, E, W), sometimes accompanied by a subtle symbol—a compass, a small map pin, or a simplified outline of the city in question. For anyone considering several personalized ideas at once, the principle is the same as with a tattoo of a loved one’s handwriting: the value lies in its exact connection to a real moment, not in how complex the design looks.
Decimal vs. DMS format: which to choose and why
There are two standard ways to write a coordinate. Decimal format expresses latitude and longitude as a single number with decimal places, for example, 40.714 for the latitude of New York City. DMS format divides each degree into 60 minutes and each minute into 60 seconds, so the same latitude becomes 40°42'51"N (source: Degrees/Minutes/Seconds (DMS) vs Decimal Degrees (DD) - GIS Geography). The conversion between the two follows a simple rule—decimal degrees are calculated as degrees plus minutes divided by 60 plus seconds divided by 3,600—and the result always describes the same point on the map. In other words, you don’t choose one format because it’s “more accurate” than the other, but for how it looks in writing and how much space it takes up.
How each format looks written on the skin
Decimal format is generally the more discreet choice: two groups of numbers separated by a comma or a period, with no extra symbols, making it easier to read at a glance in a small area. DMS retains classic navigation notation, with degree, minute, and second symbols, and tends to look more technical—a natural choice for anyone who wants the tattoo to look, visually, like a coordinate from an “old map,” rather than just a string of numbers.
How many decimal places are enough for the location to remain recognizable
The precision of a decimal coordinate depends directly on the number of decimal places retained: four decimal places correspond to a resolution of approximately 11 meters at the equator, while five decimal places bring it down to approximately 1.1 meters (source: Decimal degrees - Wikipedia). This four-decimal-place level isn’t a random approximation: the U.S. Geological Survey (USGS) officially uses it as a standard for its maps, considering it sufficient for resolution at the scale of a property (source: USGS Open-File Report 99-0557). In practice, for a tattoo, this means four decimal places are usually enough for the location to remain clearly identifiable, without cluttering the text with extra numbers that do nothing to make the location easier to recognize, but do make the string harder to read and remember.
How to find and check your location’s coordinates
The easiest place to start is Google Maps. On a computer, right-clicking the exact spot on the map opens a window showing the latitude and longitude in decimal format, ready to copy (source: Search by latitude & longitude in Google Maps - Google Maps Help). On a phone, press and hold on the map until a pin appears on the point you’re looking for, and the coordinates will automatically appear in that location’s information card. It’s worth repeating the search on two different devices or comparing the result with a second source before sending the numbers on, because the text goes directly onto the skin: a single incorrect digit moves the point described to a different place, sometimes several kilometers away, and you can’t spot the difference just by looking at the string of numbers.
Font and placement on the skin
The length of the text largely determines where a coordinate tattoo can go. DMS text, with degree, minute, and second symbols for both values, takes up noticeably more space than the decimal equivalent, so it sits more naturally on an elongated area—the forearm or ribs—than on a small one, where it would have to be made so small that it becomes hard to read. For a more limited area, the discussion in the guide to temporary tattoo sizes, from small designs to full body helps you realistically estimate how much space a text of a given length needs before you choose the final placement. As for the font, a simple style with numbers that are clearly distinguishable from one another—for example, 8 and 3, or 1 and 7—works better than an ornate font when what really matters is that anyone can read the coordinates correctly years later, not just that the first impression is pleasing.
Combining coordinates with a compass or map outline
Many people like the idea of having a symbol alongside the numbers, rather than leaving the text on its own on the skin—something that suggests the idea of a “found place.” A subtle compass next to the coordinates does exactly that, without cluttering the design, and its style can be adjusted to suit how detailed you want that area to be.
If you want to see more versions of this motif before choosing one, the Temporary Compass Tattoos collection brings together several styles, from the more detailed designs to those pared down to just a few lines.
Test the format and placement before making your final decision
A temporary tattoo with the same text and placement shows exactly how the numbers read on your skin, in real lighting and in the actual position, before you make any permanent decision. This remains strictly a test of design, size, and placement: it doesn’t predict how a permanent version of the same design will look, how long it will last, or how it will heal; it gives you time to compare the format, font, and length on your chosen area, as also recommended by the general guide to choosing a design and the right placement for your first tattoo. For a design with your own coordinates, the next step is to send the exact text you want to see tattooed—the guide to the real options for a custom temporary tattoo explains what you can request, while the article on preparing the file for a custom tattoo details exactly what text format and information to send, so the result on your skin matches what you checked on the map.
