PPI and printer DPI describe different things
Separate image pixels per inch from printer dots per inch, calculate effective PPI, and choose print settings without confusing the two measurements.

Understand the decision behind the controls. These guides use specific images and dimensions to explain what changes, what stays the same, and what to check on the finished print.
Pixels and print size: start with the image you have
Calculate physical print dimensions from real pixels, choose a useful PPI example, and understand why a larger number does not guarantee a sharper print.

Separate image pixels per inch from printer dots per inch, calculate effective PPI, and choose print settings without confusing the two measurements.
Read article →Crop to fill or keep the whole photo?
Compare fill and fit with a 4000 × 3000 photo in a 10 × 8 frame, including retained pixels, border sizes, composition, and export choices.
Read article →Print a 4 × 6 photo without surprises
Check the exact inch size, source ratio, crop, paper layout, and actual-size print settings before making a 4 × 6 photograph.
Read article →Fit a 4:3 image into a 3:2 frame
See why a 4000 × 3000 image needs a crop or side borders in a 6 × 4 frame, with exact geometry and practical composition advice.
Read article →What changing resolution metadata actually does
Understand the difference between a resolution tag, real pixel dimensions, resampling, and physical PDF placement before preparing a photo for print.
Read article →Check the original image dimensions before printing
Read actual oriented pixel dimensions, distinguish originals from reduced copies, and use manual calculations honestly when the source file is unavailable.
Read article →Why your PDF prints smaller than expected
Check PDF page size, loaded paper, Fit versus Actual size, printer margins, and calibration before changing the photograph or layout.
Read article →Understand printer margins before arranging the page
Distinguish sheet edges, printable areas, photo borders, and gaps, then check an 8 × 10 layout on A4 and Letter without assuming borderless support.
Read article →Choose a crop without stretching the photograph
Preserve proportions when changing frame shapes, compare fill and fit, position a crop deliberately, and keep the original for future sizes.
Read article →Prepare several small prints on one sheet
Calculate a repeated photo grid, keep frame size separate from image size, and print four 5 × 3.5 inch frames on landscape A4 at actual size.
Read article →Check orientation before choosing the crop
Understand image orientation, quarter-turn rotations, frame orientation, and why the final crop should be chosen after the photograph is upright.
Read article →Keep your original photo unchanged
Separate source files, session previews, saved layout parameters, optional local originals, and downloaded exports so a print task does not replace your only copy.
Read article →Read effective PPI after cropping
Calculate PPI from the retained crop and actual photo size, compare fill with fit, and see why cropping does not always lower PPI.
Read article →Is 4 × 6 the same as 10 × 15 cm?
A 4×6 inch print is 101.6×152.4 mm. Compare it with 100×150 mm, check pixels at 300 PPI, and choose the size your frame or lab actually needs.
Read article →Print two 4 × 6 photos on one A4 sheet
Arrange two true 4×6 inch photos on one A4 sheet with a 5 mm gap. Check exact placement, printable margins, PDF size, and 100% printing.
Read article →Pixels and physical size
Start with Pixels and print size if you know the image dimensions but are unsure how large to print. PPI and printer DPI separates image density from the output device, while Resolution metadata explains why changing a label does not create detail.
Check the original image dimensions before relying on a number from another copy. Effective PPI after cropping then connects the retained pixels to the physical photo rectangle.
Composition and crop choices
Compare fill and borders, work through a 4:3 image in a 3:2 frame, and position a crop without stretching the scene. The 4 × 6 guide combines exact units with a common print task. The orientation guide explains why the upright image and target orientation should be settled before refining the crop.
Paper, printing, and recovery
If a PDF prints too small, check scaling and paper selection before changing the photograph. The margins guide separates sheet edges from printable area. The repeated-layout guide calculates a complete grid, including gaps and outer spaces.
Keep your original photo explains the difference between a source, an export, saved parameters, and an optional locally stored original. Use the Docs for step-by-step operation after choosing an approach here.
