How to Use the Travel Photo Storage Calculator
Select your camera type or enter a custom file size per photo, then enter how many photos you take daily and your trip length. The calculator shows daily storage needs, total storage required, and recommends an SD card size with a 1.5× buffer for safety.
File Size by Camera Type
Smartphone JPEGs typically range from 2–5MB. iPhone 15 Pro ProRAW files run 50–75MB. Mirrorless RAW files (Sony ZV-E10, Fuji X100VI, OM-5) average 20–35MB depending on megapixel count. High-resolution bodies like the Sony A7R V (61MP) produce 80–100MB RAW files. Shooting in RAW+JPEG roughly doubles storage consumption.
Backup Strategies While Traveling
Cloud backup using Google Photos, Amazon Prime Photos, or Dropbox works well in destinations with reliable Wi-Fi. However, upload speeds in rural or developing areas can be slow — don't rely solely on cloud backup. A 1TB portable SSD ($50–$100) lets you copy cards each evening without internet. For critical trips, follow the 3-2-1 rule: 3 copies, 2 different media, 1 off-site (cloud).
Video Storage Considerations
If you shoot video, storage needs multiply quickly. 4K 30fps H.265 uses roughly 50–100MB/minute, while 4K 60fps can use 200–400MB/minute. A single hour of 4K footage can fill a 32GB card. GoPro Hero13 at 4K uses about 4–6GB per hour. Factor video time into your estimate — even 30 minutes of travel video per day adds 2–4GB to your daily storage requirement.
Frequently Asked Questions
Multiple smaller cards are safer. If a single 256GB card corrupts or gets lost, you lose everything. Two 128GB or four 64GB cards spread the risk. Label cards clearly (Day 1–3, Day 4–7) and store used cards in a separate case from empty ones. Keep one formatted spare in your bag at all times.
For burst shooting (sports, wildlife, street photography), a UHS-II V60 or V90 card is recommended. Top options include the Sony Tough Series SF-M, SanDisk Extreme Pro UHS-II, and Lexar Professional 2000x. These write at 250–300 MB/s, clearing camera buffers quickly. Budget V30 cards are fine for regular travel photography with occasional bursts.
At 100 shots/day at 30MB RAW = 42GB total. Google Photos free tier (15GB) won't be enough — consider a Google One 100GB plan ($2/month) or 200GB ($3/month). Amazon Prime members get unlimited full-resolution photo storage (no video), making it ideal for RAW backup. iCloud 200GB storage runs $3/month and syncs directly to iPhone.
