jpg export not sizing in Powerpoint

[trishaw19134217]

Hello, tried looking it up on google but didn't find any answers. I have an Indesign file letter size with art. When I export as a jpg it is letter size, 300dpi. 

When I drag the image into powerpoint it is not filling the slide, even though the powerpoint template is letter sized.

I reealize this may be a powerpoint issue, but I have done this successfully before with Indesign > export JPG > drag Jpg into powerpoint and it auto fits 100%. Except I was on PC and not mac, and also it was vertical, not horizontal page orientation.

Any help or thoughts would be appreciated. I know I can right click in powerpoint/set background image and do it that way but is arduous for the number of slides I must produce.

Thank you.

Hi @trishaw19134217 , you could test that by placing the exported jpeg back into InDesign and check its dimensions at 100% scale.

Thanks, just did that and it is the perfect/correct size. It also works portrait orientation, all other things being equal. With the same files.

But when I switch to landscape in ppt and indd and drag the jpg, it comes in at ~70%

Image "size" is something of a phantom. The only absolute is the image size in pixel height and width. Any conversion of that to a specific page, print or display size is dependent on the assigned PPI value and how the destination application interprets it.

That is, you can have an image that's 1100x850 pixels in actual size. If the PPI is set at 100, it will be read by most apps at 11x8.5 inches. But you can set the PPI to any value you like and it will not change the image itself, or its pixel size, at all. And there is no guarantee that any app (PP, Word, a photo viewer) will read and apply the PPI value.

You need to determine what PPI Powerpoint is expecting, and then export your images at a matching value for the operation to be drag-and-drop without having to resize the image.

Can't help on the Powerpoint end, but if you find that value, and need help setting your export parameters, this is the place to ask.

I tried an experiment 1.2 x bigger. Indesign is now 13.2 x 10.2. Export as Jpg. Drag jpg into powerpoint. Jpg comes in at the exact same size and dimensions in powerpoint as the 8.5 x 11 one.

It's very confusiong because everything works in portrait orientation, just not landscape

PP is clearly expecting/set to expect a different scaling. If you can determine that scaling, or set it, the process would be more seamless.

Note also that you can just adjust the export scaling and not the InDesign document settings, and get the same result. Might be easier to experiment with.

But reason #2,768 why I dislike and refuse to work in Powerpoint. 🙂

Sounds like Powerpoint isn’t seeing the JPEG’s pixel per inch output dimensions—it’s interperting the 2550 x 3300 pixel dimensions as something other than 300ppi
