500 px wide - what does this mean?

I'm curious what 500 px wide means. What does it do to the image? Is it an during the export process in Lightroom?
Thanks!

The standard "thumbnail" image that is posted on UHH is condensed to 600-pixels wide. It cannot be enlarged beyond that size, but if you check the box labeled (store original), then the tab labeled download will allow the original, larger pixel count photo be downloaded and enlarged.
You can limit the enlargement size of any digital image by reducing the pixel count in a copy. Smaller pixel count means less detail upon enlargement. 500 pixels wide is actually quite small.

500px divided by dpi=inches
inches x dpi=pixels

500pixels divided by 150dpi= 3.333 inches {example}
that is just one side of your photo.

If you want to. It is under the export dialogue.
How large do you want your images to appear on peoples screens (if web publishing)?
If printing I do not downsize the images (except to crop - if needed).

500 px is rather small and would be appropriate for emailing or as mentioned, posting to UHH if you don't want to provide a downloadable file.
One example: a bridge camera that is 12 megapixels and shoots 4:3 ratio will produce an image that is 4000 pixels on one side and 3000 on the other.
For printing you usually want all your pixels (don't downsize). A handy chart that explains:

A computer monitor displays images at 72 pixels per inch.

Pixel count is related to a sensor, or to the size (quality) of an image captured by a sensor.
Dots (of ink) per inch (DPI) is related to the quality of a print on paper. It is related strictly to the printer.
Pixel count and DPI have nothing to do with each other.

It just means the longest side of your photo is 500px
Wow, where do you people get this stuff from?

Thank you everyone!
I'm shooting products for a friend and they need to be a minimum of 72dpi and 500px.
I know I can adjust the dpi and usually export at 300. The 500px confused me.
I'm shooting with a canon 5d iii so I should be ok.
Thanks again!

They just need to be 500 pixels wide. The dpi/ppi doesn't matter a bit.

My monitors which were old would display at 92 pixels per inch. New 4K monitor for example displays much higher depending on screen size. Cell phones and tablets can exceed 300 pixels per inch.

How do I get the shot to 500 pixels wide?

In Photoshop you would click on Image, then Image Size, then change the width to 500. The menu names vary from program to program, but it's the same concept. Resize the photo to 500px wide.
