LED Size Chart: Types & Dimensions
Standard LED Sizes
Take the confusion out of choosing the right LED sizes for your project with Evan Designs’ LED size chart. Our lights come in various shapes and measurements so you’ll be sure to find the right LED light size for your application. Whether you’re searching for small LED chip lights or mega LEDs, we have the perfect fit for every project. Browse through the LED dimensions below and find out which size is right for your display now.
Z LED
This Z LED is THE smallest LED made, smaller even than our Pico. When it really has to fit a tiny space, Z to the rescue. This LED is only 0.6mm across. It's really tiny. But yet somehow it still give a nice light.
The Z is nice in tiny candles or as indicator lights, or tiny models. It doesn't give enough light to light up a room.
Pico Chip LED
The Pico chip LED is half the size of our Nano chip LED. You have to look closely at the magnet wire to even see this little LED. If you light these little picos up, then you can see it just fine! These surface mount LEDs are without the "legs". This type of LED has no metal legs extending down. The flat shape makes it very handy for small spaces.
Pico chip LEDs are also great when you need to glue them flat and have very little space. Think about the inside of a table lamp or on the front of small models. There are lots of possibilities. And the brightness is amazingly good for such a tiny LED!
Nano Chip LED
The Nano chip LED is half the size of our regular chip LED. It still gives a great amount of light in a tiny package. These surface mount LEDs are also without the "legs," so there are no metal legs extending down, and again, this flat shape is quite handy for small spaces.
Nano chip LEDs can also be glued flat where you're tight on space — once again, think of things like table lamps and small models.
Due to variations in SMD LED sizes, this should only be considered a general LED size chart.
Chip LED
The big difference with the chip LEDs is they get rid of the "legs." These surface mount LEDs have no metal legs extending down. The flat shape makes them very handy for small spaces and flat applications.
The chip LEDs are just great when you need to glue them flat. Like on a ceiling to shine down, inside of a street lamp, or on the front of a car.
And the brightness is still fantastic. 
Deka Chip LED
The Deka is bigger than the Chip and Smaller than the Mega. It's the best of both worlds. The Deka has a great brightness, 2-3 times brighter than the chip with a small form factor, smaller and easier to fit into things than the Mega.
Deka could light a whole room in 1:12 scale or a whole building in HO scale.
Mega Chip LED
Our brightest LED yet! The mega is a great choice for whole room or whole building lighting.
They are small, compact and flat for easier mounting. And very very bright! 5mm x 5mm by 2mm thick.
With these SMD Chip style LEDs, we have taken care with tolerances, adding 8 inches of red and green superfine magnet wire.
Get these chips already wired, tested, guaranteed and fully ready to connect to your power supply. No resistors need to be added, we have already added resistors if you order 5-12 volt DC or 7-19 volt AC/DC we add the resistor for you.
Note: As always, exact measurements may vary — this is a general LED size chart only.
1.8mm LED
The 1.8mm mini LED has a tip that is 1.8mm across, and below that, a square base.
If you are putting LEDs into your project from the inside, you do not need to have the whole LED showing to get a nice lighting effect. Use a 5/64 drill bit to have just the small tip of the LED showing.
You can also cover LEDs with plastic lenses. Since they do not get hot you will not have to worry about heat.
3mm LED
The 3mm LED has a rounded top that acts a little like a focusing lens. If you need more light spread, you can sand off the rounded top. Be careful not to sand down to the metal diode inside of the bulb.
If you are putting LEDs into your project from the inside, you can get a nice lighting effect even without the entire LED exposed. Use a 7/64 drill bit to have just the very tip of the LED showing, or cover it with plastic lenses. These LEDs will not get hot either.
Note: Specific measurements can differ from what we found for this LED size chart.
5mm LED
Our largest and brightest bulb style LEDs. We have tested larger bulbs but have not found any that are brighter than these 5mm LEDs we carry.
The 5mm LED has a rounded top that acts a little like a focusing lens. If you need more light spread you can sand off the rounded top, but be careful not to sand down near to the metal diode inside of the bulb. Or consider our SMD LEDs above.
Also, keep in mind that you do not have to have the whole LED showing to get a great lighting effect. Use a 3/16 drill bit to have just the very tip of the LED showing and still create a nice effect, or try covering your LEDs with plastic lenses. These lights don’t get hot, so you will not have to worry about heat.
AC/DC LEDs
If you are getting our AC/DC LEDs for power packs, this is the dimension of our compact rectifier circuit board.
The board is only found on AC/DC LED units, located about 3 inches away from the bulb.
Why a rectifier for AC? AC power has switching polarity that will kill an LED. And non-regulated power supplies, such as slot car tracks, model trains or doll house power supplies, can also damage and kill an LED.
This little circuit will protect your LED for years of trouble-free use!
How to Wire Multiple LEDs
** Wire your LEDs in Parallel **
When wiring multiple LEDs the way you connect them is referred to as wiring your LEDs in Parallel. In a parallel circuit all the positive or Red wires are connected back to the positive connection to your battery or Wall Adaptor and all negative wires will lead to the negative connection of your power supply as shown in the following picture.
