Image sizing01
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 ↗Screen typography40
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 ↗Imposition48
Circle Label Area
A circular label's trimmed face area follows its diameter.
Open calculator ↗Image sizing49
CMYK Raster Buffer Size
A four-channel uncompressed pixel buffer provides a baseline CMYK data-size estimate.
