Hi,

What is the optimal size for item images? We are going to add images to our items, and would like to learn how to find the best balance of file size versus image size.

We are concerned about the impact of uploading many large, hi-res images on the database. Does anyone have any experience with this? 

Best regards,
Lars.

That depends on your use. If it identification, smaller images are fine, especially if you use handheld devices in manufacturing or warehouse. If you use them for quality comparison of fine details, use a higher resolution. The answer also depends on how many items you have in your inventory list.

For screen display, 72 dpi. For printing, 300 dpi.

Hi Lars,

It depends entirely on what the images are used for. If they’re for basic thumbnail surfacing on PDF or Word reports or eCommerce thumbnailing, etc. then you’d probably be looking at something to the effect of:

Aspect Ratio: 1:1
Dimensions: 1000×1000 pixels [N.B. this is what Amazon’s larger product photo size is, if eCommerce is your intent]
Resolution: 72 PPI
Bit Depth: 24-bit
Format: JPG
Compression: ~70% (Baseline Optimized Level 9 in Photoshop)
Colour Mode: RGB (optimal for digital display) | CMYK (optimal for print)

This tends to be a happy place in terms of decent quality and file-size.

However if this is for serious cataloguing (i.e. potentially used for commercial print or even printing on banners, etc.) you’ll want to explore lossless 300-PPI CMYK-supporting formats with decent compression algorithms (like TIFF). However, if this were your use case, I’d probably be recommending using the NAV image for a lossy thumbnail and storing the higher-res versions outside of your database.

Just my $0.02.?
