Pixels to Print Centimetres

Pixel count becomes a physical print dimension only when paired with an image density.

Open calculator ↗
Image sizing02

Print Centimetres to Pixels

A physical output target determines the minimum whole-pixel dimension at a selected density.

Open calculator ↗
Image sizing03

Effective Image PPI

Effective resolution depends on how large an image is placed on the page.

Open calculator ↗
Image sizing04

Enlarged Image PPI

Enlarging a placed image spreads its existing pixels over more physical space.

Open calculator ↗
Image sizing05

Image Megapixels

Total pixel count describes the size of a rectangular raster grid.

Open calculator ↗
Image sizing06

Aspect Ratio Target Width

A proportion connects the desired width to a known height.

Open calculator ↗
Image sizing07

Aspect Ratio Target Height

Keeping an aspect ratio avoids stretching a composition during resizing.

Open calculator ↗
Image sizing08

Proportional Resize Height

A width-led resize preserves the original relationship between horizontal and vertical dimensions.

Open calculator ↗
Page setup09

Bleed Document Width

Bleed extends artwork beyond both cut edges, increasing the total document width.

Open calculator ↗
Page setup10

Bleed Document Height

The top and bottom bleed areas add to the trimmed height.

Open calculator ↗
Page setup11

Live Area Width

The live area is the horizontal space remaining after margins are removed.

Open calculator ↗
Page setup12

Live Area Height

Vertical margins define the available content height within a page.

Open calculator ↗
Layout grids13

Column Width

Equal columns divide the usable width after the gaps between columns are removed.

Open calculator ↗
Layout grids14

Grid Gutter Width

A target column width leaves the remainder to be shared by internal gutters.

Open calculator ↗
Typography15

Baseline Line Count

A baseline interval gives a rough count of full line boxes in a fixed-height frame.

Open calculator ↗
Typography16

Leading from Font Size

A proportional leading rule gives a starting line spacing for a text style.

Open calculator ↗
Typography17

Leading Percentage

Expressing leading relative to font size makes spacing systems easier to compare.

Open calculator ↗
Typography18

Points to Millimetres

A PostScript point is one seventy-second of an inch.

Open calculator ↗
Typography19

Millimetres to Points

Converting a physical measurement into points supports page-layout settings.

Open calculator ↗
Typography20

Picas to Points

One pica contains twelve points in modern publishing measurement.

Open calculator ↗
Typography21

Tracking Width Change

Tracking adds spacing across the gaps in a run of characters, often in thousandths of an em.

Open calculator ↗
Typography22

Modular Type Scale

A modular scale generates related sizes from one base and a repeated ratio.

Open calculator ↗
Typography23

Text Block Height Estimate

Counting full line boxes provides a rough vertical allocation for body text.

Open calculator ↗
Typography24

Characters per Line Estimate

An average glyph-width assumption estimates text capacity across a measure.

Open calculator ↗
Print quantities25

Sheets for Page Count

A physical sheet can carry multiple logical pages depending on imposition and duplexing.

Open calculator ↗
Print quantities26

Saddle-Stitch Page Padding

A simple folded-sheet booklet needs a page count divisible by four.

Open calculator ↗
Print quantities27

Signature Count

A signature groups a fixed number of pages into a folded section.

Open calculator ↗
Paper28

Paper Sheet Weight

Grammage gives mass per square metre, so sheet area determines nominal weight.

Open calculator ↗
Paper29

Paper Stack Weight

Stack mass follows single-sheet mass times count.

Open calculator ↗
Paper30

Paper Stack Thickness

Caliper directly estimates the height of a stack of sheets.

Open calculator ↗
Binding31

Book Block Spine Estimate

A leaf has two pages, so page count first becomes a leaf count before applying caliper.

Open calculator ↗
Binding32

Cover Spread Width

A flat front-spine-back cover combines two panel widths and the spine, with outer bleed.

Open calculator ↗
Imposition33

Business Cards per Sheet

Two uniform grid orientations can be compared for a quick card layout count.

Open calculator ↗
Imposition34

Label Grid Count

Repeated pitch cells provide a regular sheet label count.

Open calculator ↗
Print quantities35

Production Sheet Count

An order quantity plus an explicit allowance becomes a whole-sheet production estimate.

Open calculator ↗
Print quantities36

Ink Coverage Equivalent Area

Coverage-weighted area expresses how much fully covered area a layout represents mathematically.

Open calculator ↗
Paper37

Print Run Paper Area

Summing sheet area describes the total paper surface in one side of the stock.

Open calculator ↗
Planning38

Production Cost per Unit

A complete production estimate can be allocated across the finished quantity.

Open calculator ↗
Planning39

Total Print Cost

A fixed-plus-variable model shows how a setup cost is spread across a run.

Open calculator ↗

CSS Pixels to Points

CSS defines a reference relationship of ninety-six pixels to one inch and seventy-two points to one inch.

Open calculator ↗
Screen typography41

Points to CSS Pixels

The CSS reference-unit relationship converts points into CSS pixels.

Open calculator ↗
Screen typography42

Pixels to Rem

A rem unit is relative to the root element's computed font size.

Open calculator ↗
Screen typography43

Rem to Pixels

Multiplying a rem value by the root size gives its current CSS-pixel equivalent.

Open calculator ↗
Screen typography44

Viewport Width Units

One viewport-width unit equals one percent of the relevant viewport width.

Open calculator ↗
Screen typography45

Device Pixel Export Width

An image export can target enough device pixels for a chosen CSS display width.

Open calculator ↗
Layout grids46

Print Scale Percentage

A target dimension determines the linear scale percentage for proportional resizing.

Open calculator ↗
Layout grids47

Area after Scaling

Area changes with the square of a proportional linear scale.

Open calculator ↗
