Couples ask this when the photographer USB arrives, or when a guest video fills a phone before they can send it.

Most couples need 5 to 15 GB for a normal wedding, and video is what moves the total. Storage is one half of the collection decision covered by How to Collect Wedding Guest Photos with a QR Code — the counts and the QR card math live there too.

Use the calculator first

Move the sliders. You will see three piles: the photographer gallery, guest photos, and guest videos. The USB size is the drive that actually fits the pile with room left over.

A 16 GB stick looks big until you try to copy 14 GB onto it. Leave headroom.

This is not the same question as How Many Photos Does an Average Wedding Have?. That page is about count. This page is about gigabytes.

The two galleries take different space

Photographer files are larger. A delivered JPEG from a full-day wedding is often 6 to 12 MB. Guest phone photos are smaller, often 2 to 6 MB, but there are more of them.

That is why a 500-photo photographer gallery and a 1,000-photo guest gallery can land in a similar number of gigabytes.

If you only keep the paid gallery, a 16 GB USB is usually enough. If you also keep every guest candid, plan larger.

Photographer files, in gigabytes

Most full-day photographers deliver about 50 to 80 finished photos per hour. At 8 MB each, an 8-hour day is about 4 GB of JPEGs.

Those hours come from your photo timeline. Wedding Photo Timeline Calculator: Free Hour-by-Hour Plan works out the coverage your day needs, which is the other half of this math.

A second shooter adds another 2 to 4 GB.

RAW files are a different story. One RAW can be 20 to 50 MB. Couples almost never need those. Ask for the edited JPEGs unless you are reprinting at poster size and your photographer agrees.

Highlight video from a videographer is often 4 to 12 GB for a short film. The working files they edit from are much larger. You do not need those unless you hired them to hand over the project.

Guest photos add up faster than they look

A 100 to 150 person wedding often produces 1,000 to 5,000 extra phone photos. At 4 MB each, 2,000 guest photos are about 8 GB.

That guest count is also your table count. Wedding Table Count Calculator: How Many Tables You Need turns it into the tables, chairs, and linens to order. Hosting it under a tent? Free Wedding Calculators chain the same headcount through seating, tent size, and cake servings.

Most of those files never leave the phones. A group chat compresses them. AirDrop fails at the hotel. Someone says they will send a folder next week and does not.

A QR gallery is how you keep the guest half at full size. Guests scan with the camera. No app. No guest account. The files land in one private album instead of 40 camera rolls.

Video is the storage surprise

A 30 to 60 second phone clip is often 40 to 120 MB. Twelve of those clips are about 1 GB. Forty clips can beat the photographer JPEG gallery by themselves.

If a few guests record toasts, first dance, or speeches, budget video on its own slider. Do not guess from photo count.

Keep video in the same gallery as the photos. Splitting them across Drive folders and iMessage threads is how files disappear.

What USB size to buy

Use the calculator, then round up.

Under about 12 GB: a 16 GB drive

12 to 24 GB: a 32 GB drive

24 to 50 GB: a 64 GB drive

More than 50 GB: 128 GB, or skip the stick and keep a private gallery plus a hard drive

Buy two cheap USBs rather than one fancy one. Label them. One stays with you. One goes to a parent or a fireproof box.

Cloud is the third copy, not the only copy. Links expire. Passwords get lost. Download the photographer gallery the week it arrives.

How many photos fit on a 16, 32, 64, or 128 GB drive

Couples usually ask this the other way round. Not "how big is my pile" but "will the 32 GB drive I already own hold it". Working backwards from file size is the fastest check, and it is the same math the calculator runs.

1 GB: roughly 130 to 340 photos at 3 to 8 MB each.

16 GB: about 2,000 to 5,400 photos at 3 to 8 MB each.

32 GB: about 4,000 to 10,900 photos at 3 to 8 MB each.

64 GB: about 8,200 to 21,800 photos at 3 to 8 MB each.

128 GB: about 16,400 to 43,600 photos at 3 to 8 MB each.

Those ranges assume phone-sized files. If you are counting the photographer set at 6 to 12 MB an image, halve them: a 64 GB drive holds roughly 5,300 to 10,900 of those, and a 32 GB drive about 2,700 to 5,400.

Kingston publishes the same chart on different assumptions and lands on 53,571 photos on 64 GB at 12 MP, alongside only 800 uncompressed RAW files for that identical drive. Both numbers are right. File size is the entire difference, which is why no single capacity answer fits every wedding.

RAW is the number people underestimate. At 20 to 50 MB a file, 1,000 RAW images eat 20 to 50 GB on their own. Those are working files from the photographer, not your keepsakes. Ask for the edited JPEGs.

What 1,000, 3,000, and 10,000 photos take up

Same math, from the other direction. These are the numbers people look up after a phone says the storage is nearly full.

1,000 phone photos: about 2 to 4 GB at 2 to 4 MB each.

3,000 phone photos: about 6 to 12 GB.

10,000 phone photos: about 20 to 40 GB.

1,000 delivered photographer JPEGs: about 6 to 12 GB at 6 to 12 MB each.

1,000 RAW files: about 20 to 50 GB.

iPhone photos are usually HEIC rather than JPEG now, at about 1.5 to 2 MB each, so 3,000 of them can sit under 6 GB. Most Android phones still write JPEG at 3 to 5 MB, and a high-resolution mode writes larger files still.

A wedding pile is almost never one file type. Budget the guest photos at phone size, the photographer gallery at delivered-JPEG size, and any RAW or video in a category of its own. That is the mix the calculator above is adding up.

The 3-2-1 rule without the lecture

Keep three copies. Use two kinds of storage. Keep one copy off the laptop.

A working version: photographer download on your computer, a USB or SSD in a drawer, and the live gallery online. That is enough for almost every couple.

Do not make Google Drive the whole plan. Free accounts fill up. Shared folders get mystery permissions. A private wedding gallery is built for this pile. A generic cloud folder is not.

What not to do

Do not send the full gallery through WhatsApp or iMessage. Those apps shrink files.

Do not keep the only copy on the photographer’s proofing site. Most of those links die in 12 to 24 months.

Do not make a new gallery for every table. Storage is not the problem then. Finding the files is. One unique wedding photo QR code, printed across the room, keeps one pile.

Do not mix seating charts or RSVP tools into the photo gallery. You need the photos and videos in one place. Extra products scatter the day.

Do not budget disposable cameras as your storage plan either. Film is a per-table cost with a 27-frame ceiling — Disposable Cameras vs QR Code at a Wedding runs that math against one flat gallery.

A simple weekend plan

Before the wedding, create the gallery and print the table cards.

During the wedding, guests add photos and clips while they still care.

The week after, download the photographer set. Copy it to the USB the calculator recommended. Confirm the guest gallery is still filling in.

On your anniversary, open the USB and the gallery once. If a drive failed, you still have the other copies.

Questions couples ask before they buy a drive

How much storage do wedding photos need? For an average 120-guest, 8-hour wedding, plan about 7 GB for JPEGs plus a handful of guest clips. Buy a 16 GB USB, or 32 GB if you expect a lot of video.

Do I need a terabyte? No. That is photographer archive talk. Couples need tens of gigabytes, not a studio backup.

What about RAW? Skip it unless you have a reason. JPEGs print well and take a fraction of the space.

Can guests upload without an app? Yes. The camera on a modern phone opens the gallery in the browser. No account.

Should welcome-dinner clips live somewhere else? Only if you want a separate album. Otherwise keep one gallery for the weekend.

How many photos fit on a 64 GB drive? About 8,200 to 21,800 at 3 to 8 MB each, or closer to 5,300 to 10,900 if they are 6 to 12 MB delivered JPEGs. Pressed into RAW files, the same drive holds only about 1,300 to 3,300.

How much storage do I need for 3,000 photos? About 6 to 12 GB if they are phone photos at 2 to 4 MB each, and 18 to 36 GB if they are 6 to 12 MB photographer JPEGs. Leave the drive at least a tenth empty either way.

How long do photographers keep wedding photos? There is no industry standard, and it is shorter than most couples assume. Gallery windows of a month to a year after delivery are commonly reported, unedited RAW files go sooner, and a studio that closes takes its archive with it. Download the delivered set in the first month and keep your own copy.

Do iPhone photos take less space than JPEGs? Usually yes. iPhone photos are HEIC by default at about 1.5 to 2 MB each, while a 12 MP JPEG is often 3 to 4 MB. That is how 2,000 guest iPhone photos can land under 4 GB.

Guest count ranges, in gigabytes

These ranges assume edited JPEGs from one photographer, phone photos in original size, and a modest number of clips. They match the calculator defaults.

A 50-guest brunch wedding with 5 hours of coverage is often 2 to 4 GB. A 16 GB USB is plenty.

A 120-guest Saturday with 8 hours is the average we use in the calculator: about 4 GB from the photographer, 2 GB of guest photos, and 1 GB of clips. That is why 16 GB still works, and 32 GB is the calm buy.

A 200-guest wedding with a second shooter and 12 hours can land at 10 to 20 GB before video. If uncles record speeches, jump to 32 GB.

A 300-person tent wedding with a videographer highlight film is a 64 GB problem, not a 16 GB problem. The film is the jump, not the extra 100 guests.

If your photographer delivers 1,200 images, ignore the “average wedding” USB advice and run the sliders.

File size is not quality

A 4 MB guest photo can be the best picture of the night. A 40 MB RAW can be a duplicate of a JPEG you already have.

Storage planning is about what you will actually open in five years. Couples open JPEGs and short clips. They do not open RAW catalogs.

Ask the photographer, in writing, for full-resolution JPEGs and the length of time the online gallery stays live. Download in the first month.

If a guest uploads a 4K clip of the vows, keep it. That one file is worth more than 200 similar dance-floor bursts. You can delete bursts later. You cannot rebuild a vow clip that never left a phone.
