How to export an image in photoshop that is the same size as the original size?

If you are working in inches in both Photoshop and InDesign, it should be no problem…designers have been successfully doing it for almost 25 years. But whether that information gets to InDesign can depend on how you exported it.

After you rasterize it in Photoshop, what does it say in Image > Image Size after you set Units to Inches? Are the numbers as in the picture below, and if not, how is it different? (The most important thing is that Image Size says it’s 19 inches by 8 inches, the Resolution is not as critical.)

Next question: You said you are “exporting” it, but there are many ways to do it in Photoshop. Which way are you exporting?

A. File > Save As or File > Save a Copy

B. File > Export > Save for Web (Legacy)

C. File > Export > Export As

D. Something else

One thing I am suspecting is that the rasterized file is OK, but, maybe an exporting method was used that does not include the ppi resolution metadata. Because if the ppi metadata is left out, the default dimensions in InDesign may not be as expected. For example, if you had used File > Export As, it’s designed for online media and not print, so ppi resolution data is not included in the exported file.

The recommended way, for print dimensions, is to use File > Save As or File > Save a Copy. When used with a format such as PSD, TIFF, or JPEG, these commands preserve ppi metadata and so they should come into InDesign with the same inch dimensions that were specified in Photoshop.

One more thing: Is there a reason you chose to add the step of rasterizing the PDF? Because usually, the best practice is to place the PDF directly into InDesign, to preseve all original data and also preserve smooth scalability (by not rasterizing any vector graphics or type in the PDF).

Photoshop measure documents in pixels, and InDesign/PDF uses inches. Did you get a dialog to set ppi when you imported the PDF?

Hi @john34320988gy88. Did you compare the ppi of the image in Photoshop to InDesign? Are they the same? Are you placing the Photoshop rasterized image as a PDF into InDesign, or as an image file (PSD, JPG, TIF)?
