For this project the Board Outline in EasyEDA is showing correctly when I do photo view, and when I start to generate the gerber files and it gives a preview of the top of the board., but when I create the Gerber and click through to order from JLCPCB the board outline is no longer corrrect [https://easyeda.com/winkleink/WS2812b-vertical-board](https://easyeda.com/winkleink/WS2812b-vertical-board) In EasyEDA the board is 15.75mm x 9.14mm In JLCPCB the board is 16mm x 19mm The height is not being honored by JLCPBC from EasyEDA UPDATE: I uploaded the Gerber zip to OSH Park for comparison and it too adds to the height of the PCB. Sounds like the problem is at the EasyEDA side.  It may be I've done something wrong in the design of the PCB, but the EasyEDA photo view is showing the board as I wish it to be so strange when it's a Gerber that it becomes different. Update: added images of the PCB layouts Bliue is EasyEda Green is JLCPCB   Any thoughts or ideas why this is happening. The goal is for the PCBs to be as small as possible so as not to interfere with the LEDs NOTE: I'm making a small PCB to take a WS2812b RGB LED. The board is double sided but an LED will only be on one side. The idea for the board is that using rods you can make a column of RGB LEDs by alternating the board orientation. All this to let you know the net is definitely wrong. Thanks.
