16x24 Print Size in Pixels at 300 DPI
16×24 at 300 DPI is 4800×7200 pixels — a 2:3 poster shape, like 12×18 and 8×12, not 4:5. Check the pixel math before you list this size.
Direct answer
A 16×24 inch print at 300 DPI is 4800×7200 pixels in portrait, or 7200×4800 in landscape. The ratio here is 2:3 — the same family as 12×18 and 8×12, not 16×20. Crop to 2:3 around the subject, starting from a file that still holds 4800 pixels on the short side once that crop is applied.
16×24 shows up often in poster frames, and in IKEA-style 40×60 cm equivalents. Sellers sometimes bolt it onto a listing that already has 16×20, on the logic that "sixteen is sixteen" — but the second number changes the whole composition.
It also demands a lot of resolution. Getting 4800 pixels on the short side after a 2:3 crop is more than a lot of phone photos have left to give. Better to be upfront about it: a sharp 12×18 will outperform a soft 16×24 in reviews every time.

16×24 vs. 16×20 vs. 12×18
16×24 is 2:3, working out to 4800×7200 at 300 DPI. 16×20 is a 4:5 ratio at 4800×6000, and 12×18 is 2:3 again, at 3600×5400. In other words, 16×24 is the bigger sibling of 12×18 — not of 16×20, despite the shared "16."
If your original is a standard 35mm-style 2:3 shot, 16×24 makes better use of the frame than 16×20 does. But if 8×10 is already your hero listing, 16×20 shares that same crop family instead — see 12×18 vs 16×20 for the full comparison.

| Size | Portrait pixels | Short side |

| 12 × 18 in | 3600 × 5400 | 3600 px |

Check the original before listing 16×24
Divide the short side of your crop by 300. If that number lands under 16 inches, you don't actually have a true 300 DPI 16×24. A lot of 12 MP 4:3 phone photos come in around 3000×4000 — after a 2:3 crop that might leave roughly 3000×4500, which is a sharp 10×15, not a 16×24.
Resist the urge to upscale 3000 pixels to 4800 and stamp 300 DPI on it anyway — that's exactly where soft prints come from.
Exporting 16×24 from Reopic
Open Studio, pin the subject, and add 16 × 24 in. If the original has enough resolution, add 12×18 in the same session so both 2:3 sizes share the same pin. Pro ($33 lifetime) zips up a full catalog when you're working through a large body of paintings.
Shipping and viewing distance
16×24 often ships rolled in a tube, but that doesn't lower the bar on DPI — plenty of 16×24 prints still end up framed at eye level in a hallway. Viewing distance forgives more at 24×36 than it does here.
If your actual listing is 40×60 cm, note that this converts to 15.75×23.62 in — not an exact match for 16×24. Export to whatever unit you're actually listing in; custom ratios exist for exactly this kind of mismatch.
FAQ: 16x24 print size pixels 300 DPI
How many pixels is 16x24 at 300 DPI?+
4800×7200 pixels in portrait, or 7200×4800 in landscape.
Is 16x24 the same as 16x20?+
No — 16×24 is a 2:3 ratio, while 16×20 is 4:5. They're different shapes despite the shared first number.
Is 16x24 the same as 12x18?+
Same 2:3 ratio, different size. 12×18 is 3600×5400, so scaling that up to 16×24 without more resolution would only give you 150 DPI.
Can a phone photo make 16x24?+
Some can, but only from the original camera file — not a social media download. Check how many pixels are left on the short side after a 2:3 crop.
