How many photos will your wedding produce?

For a typical 100-guest wedding, guests’ phones alone produce roughly 300 to 600 photos — a range based on real upload data from weddings collected through Wedding Arrivals, and the calculator’s default. Add a professional photographer (most deliver several hundred edited photos for full-day coverage) and a photo booth, and the total often passes 1,000. Your crowd still moves the number, which is why every figure here is adjustable.

It multiplies your guest count by the share of guests who take photos and by the photos each of them takes, adjusted for how long the celebration runs, then adds the photographer, photo booth, and disposable cameras as separate sources. The guest-behavior defaults come from real upload data from weddings using Wedding Arrivals, a QR-code photo collection service — and every number is visible in the “Adjust the numbers” panel and editable; the presets only prefill them. The result is shown as a range because even with real data behind the defaults, no two crowds behave the same.

Most wedding photographers deliver roughly 50 to 100 edited photos per hour of coverage, so a full 8-hour day commonly lands between 400 and 800 delivered images. They typically shoot far more raw frames than that and cull down to the keepers, so "photos taken" and "photos delivered" are very different numbers — this calculator estimates delivered. Packages vary widely, so check your contract and adjust the per-hour figure in the “Adjust the numbers” panel to match.

It depends almost entirely on the crowd — but real upload data gives a baseline. Across weddings collected through Wedding Arrivals, roughly half of guests take photos at all, and those who do take a handful to a couple dozen across the day. A young crowd at a party-heavy reception takes far more; an older crowd at a formal ceremony takes far less. That spread is exactly what the low-key, typical, and snap-happy presets model.

In real uploads to Wedding Arrivals albums, a smartphone photo typically runs 3 to 5 MB, so 1,000 photos need roughly 4 to 5 GB. Video is the real storage cost: a single one-minute clip can exceed 100 MB, so even a modest number of guest clips can outweigh all the photos combined. The calculator totals both using average file sizes you can adjust.

By default, most guest photos never reach the couple — they stay on individual phones or trickle in through group chats for weeks. The reliable fixes are to give guests one obvious place to put photos: a shared cloud album, or a QR-code photo collection service such as Wedding Arrivals, where guests scan a printed code and upload from the browser without installing an app or creating an account.

Each disposable camera gives you exactly 27 exposures, and in practice a good share of those come out dark, blurry, or of the ceiling — flash-free indoor shots are hard for fixed-focus cameras. Couples who use them usually value the aesthetic and the surprise factor rather than the photo count. If your goal is volume and quality, guests’ phones plus a collection plan deliver far more.

Because even real data cannot know your specific crowd. The defaults are grounded in upload data from real weddings using Wedding Arrivals, but your guests, venue, and timeline will move the number. The range spans about 30% either side of the midpoint; treat the low end as a quiet crowd and the high end as a lively one, and tune the numbers to move the whole range.
