Creating a 300dpi png in photoshop
Ive creating an email footer in Photoshop. The footer is 650px W x 300 px H. I want to set the resolution of the footer to 300dpi so that the text is readable at a smaller size, but when i do so the size of the canvas area doubles.
I will be exporting this as a .png, is there any way to get a 300dpi 650x300px footer without it becoming 1300x600px ?
Change the resolution setting to 300.
Leave the measurement at pixels/inch. Notice that the size of the image goes from 8" Ã— 10" to 4" Ã— 5", as shown below. Thatâ€™s because youâ€™re only changing the distance between pixels as you modify the resolution of the file. You have fixed overall pixel dimensions of 1200 Ã— 1500. When you set your resolution to 300 ppi, the math dictates that the image is 4" Ã— 5" (4" Ã— 300 ppi = 1200 pixels, and 5" Ã— 300 ppi = 1500 pixels). When the resolution is set to 150 ppi, the image must be 8" Ã— 10" in size (8" Ã— 150 ppi = 1200 pixels, and 10" Ã— 150 ppi = 1500 pixels).
