Many modern smartphones use the 4:3 aspect ratio by default, so you’ll again need to remember that crops will occur in your photo if you print it out as a 4×6. If your camera has a 4:3 aspect ratio, you’ll have to deal with a cropped image at both the top and bottom if you print a landscape photo and on the left and right edges if you print a portrait image.ĭo Smartphones Use the Same Aspect Ratios as Most Cameras? However, some manufacturers - such as Olympus - use 4:3 instead. 3:2 is represented by the green line.ģ:2 was the default aspect ratio for older 35mm cameras, and that remains the case for most DSLR and mirrorless cameras today. In simple terms, this means that the shot you captured is three units wide for every two that it is across for landscape orientation photos or two wide for every three across for photos captured in portrait orientation. Generally speaking, a higher resolution will improve the quality of your print up to a certain level while lower resolutions will impact your photo print negatively by producing blocky, pixelated results.Īs stated earlier, 4×6 photos have a 3:2 aspect ratio. However, you’ll want to use a higher resolution for pictures that people will hold in their hand and/or view from a close distance (which they typically will do with a print of this size). If others will view your picture from further away, you can get away with using resolution at the lower end of the scale. If you have a low-resolution photo, however, an image size of around 480×640 will be passable at 115dpi, but you’re pushing a fine line if you go lower than that in most cases. A resolution of 1024×768, or photos produced by a 0.8-megapixel camera, will also provide good results. It would be best to consider where people will see your picture, though, because you can get away with a lower resolution in some scenarios.Īs a general rule of thumb, 1200×1800 (or 1200×1788) is the minimum resolution that is recommended for 4×6 prints as it will provide 300dpi (dots per inch). If you want to achieve the best possible results when printing your photos, resolutions are arguably the most crucial area to consider. What is the Best Resolution for Printing 4×6 Photos? As for precise millimeter dimensions, 4×6 photos are 101.6×152.4mm.
PHOTO PRINT SIZE HOW TO
Ignoring the slight discrepancy you may find, though, here is how to covert the 4×6 from the Imperial system (on which its name is based) to the metric system: In centimeters, the 4×6 size for an image roughly translates to 10x15cm. The photography printing industry adopted these standard dimensions based on the aspect ratio of the viewfinder in most early digital cameras. Instead, it often measures approximately 4″ x 5 ⅞”. How Big a 4×6 Photo in Different Units of Length?īefore we continue, it’s worth noting that 4×6 photo print sometimes isn’t strictly four inches by six inches. Photo albums are commonly designed for 4×6 prints. The 4×6 photo size had (and still has) several other advantages cost-effective production is perhaps the largest.
