Hello everyone
I need to make a world map like this on in the picture, but I don't know if I should look for an specific projection or ArcGis configuration.
*This is myu first post on this forum... please be gentle*

WGS 84 / PDC Mercator - EPSG:3832
right-click on the Map title in the table of contents
Select "Properties", "coordinate system"
do the scrolling-thing until you find the highlighted one below.
There are couple ways you can do this... I suggest the following workflow by customizing one of the existing projected coordinate systems designed for the world maps.
Just a tip or two on map projections (PCS) that are good for the world maps...
For thematic and general maps, select one with curved edges (pseudocylindricals), use cylindricals (aka "map in the box") for some rare phenomena that is based on longitude, and choose Mercator only if you are creating a sea navigation chart. Here is the list of Supported map projections. Each has Usage section, which gives you hints on appropriate usage.
I hope this helps...
