Want to text, via computer, a .jpg image to granddaughter's phone. What resolution, and physical scan size should this be.
As in what is the largest image size that will not overwhelm.

Background .. We don't text (gasp ;-) but Verizon allows one to text to a phone number, from e-mail, if recipient is also on Verizon.
 
That will depend on Verizon and the phone.
What is the phone's screen size?
What are Verizon's limits for attachments to texts?
 
Can't you just email it? Many people can receive emails on their phones.
 
ah, I'll text an ask her. thanks ..
We do not have i-phone, and use flip flop rarely.
 
If the attachment is too big it will get bounced. Both texted or emailed. I can’t remember the size limitation, though. Sorry.
 
If you know what her phone takes for its own picture resolution, you will not have a problem sending a photo of that size to her...in SMS or email
 
I confirmed that anything over 10,000 pixels will cause the iPhone to go into a panic. It will send and show the preview but not open.

So no 2400 DPI 4x5 scans XD

In general the resolution limit of your scanner is about 2400-3200 pixels per inch. For 35mm that's not super big, for 120 you'll get about 6-7k pixels square. I usually resize down to 2500 pixels when I send via iMessage.

FYI some MMS messages get compressed, in other words the phone/network will automatically squish it down. For those you can send a link (e.g. with Google Photos sharing).
 
“Physical size” is irrelevant as the phone will rescale any image to fit the screen. Aim for about 6-10 megapixels or so. 3000 x 2000 should be adequate.
 
Current iPhones have 12 MegaPixel cameras...their messaging capabilities and email should be able to cope with that!

But I just read a post by someone, stating, " The photo on my Pixel is 4.77 MB and 4032x3024 pixels. What my brother received was 100 KB and 384x512 pixels." So it sounds like SMS protocols resize photos to its own 'manageable size'!
 
If you open a texted image on your computer thru a Browser it can be very obvious. I text thru chrome often and just drop images in when needed, they will get reduced sometimes dramatically in both size and IQ.
 
Surely Whatsapp is your friend. You can use it from a smart phone, tablet, or PC (desktop or laptop). I thought texting and multimedia messaging went out circa 2008?
 
Assuming the photo is in the 2:3 aspect ratio (same shape as 35mm film and many digital sensors), then I suggest a resolution of 1200 x 1800 pixels. That is enough pixels to show at a decent size on most screens, and also allows one to make a nice 4" x 6" print and a little bigger in many cases.

If the image is exported as a JPEG, Quality = 85, the file size will be something around 0.80 to 1.6 MB which should not be a problem for transferring by internet.

RE: "... what is the largest image size that will not overwhelm." - three possible bottlenecks to consider:
Your internet service provider or email service may have a maximum file size that will block emails if they include an image that is too big.
Her internet service provider or email service may have a maximum file size that will block emails if they include an image that is too big.
If either party does not have broadband, sending multiple large files may be allowed, but may slow down the user's computer/phone etc. while the images are being sent or received.

I have not investigated the finer points of sending photos by text (multimedia messaging), so there may be another set of rules to consider for texting.
 
A little Googling found <this link> where Verizon says:
--
The maximum file size that can be sent from an email to a device as a multimedia message (MMS) is 3.5 MB.
Larger files can be sent via email to email.
If a device sends a file to another device with a lower file size limit, the file is reduced to a file size acceptable by the receiving device.
Many devices are capable of sending messages that exceed intercarrier file size limits (typically 300-600 KB). A message that exceeds the other carrier's limits may be rejected and won't reach the intended recipient.
Note Lowering the camera resolution before taking pictures reduces image file size.
