How Much Storage Do You Need for Photo Backup?
As smartphone camera quality improves, individual photo file sizes keep growing too. Thousands of casually snapped photos can quietly fill up storage before you notice. This calculator takes your photo count and average file size and instantly tells you the total cloud storage needed along with a recommended plan.
Photo Size Varies by Shooting Mode
Standard auto-mode photos are usually 3-6MB, while high-quality mode, Live Photos, or portrait mode can push files to 8-15MB. Shooting in RAW format can reach 25-45MB per photo, multiplying your storage needs even with the same photo count.
Is Free Storage Really Enough?
Most cloud services offer 5-15GB of free storage. But that same account often also holds email attachments, documents, and other backups, so free space runs out faster than expected. Calculating ahead of time when you'll need to upgrade or clean up photos helps you avoid a failed backup at the worst moment.
