MEASUREMENT WORKSHOP
Free DIY measurement tools
No registration, tracking or paywall. Our calculators perform basic arithmetic and our printable worksheet records your measurements; check final order measurements with your product vendor.
Window Screen Mesh & Spline
Plan mesh cut size, frame perimeter and extra spline.
Open tool ↗Tape Measure Fraction Converter
Convert fractional inches, decimal inches and millimeters before entering your measurements.
Open tool ↗Multi-Screen Materials Planner
Plan mesh cut sizes and total spline for up to 10 removable screens.
Open tool ↗Screen Measurement Decision Assistant
Determine which measurements to record when the old frame is missing, using hardware-specific manufacturer guidance.
Open tool ↗Blind Measurement Helper
Record three widths and heights for inside mounting.
Open tool ↗Door Seal Length
Add jambs, header and a customizable waste allowance.
Open tool ↗Frame Diagonal
Check a theoretical screen frame diagonal.
Open tool ↗Door Bottom Gap Checker
Compare three gap readings and spot threshold variation.
Open tool ↗Printable Measurement Worksheet
Document screen, blind or door measurements and print a clear project record.
Open tool ↗Outside-Mount Blind Coverage Planner
Estimate coverage width and height from window opening and chosen overlaps.
Open tool ↗Phifer Screen Spline Chart Lookup
Look up published Phifer frame-and-mesh combinations; unsupported combinations show no result.
Open tool ↗Which calculator should I use?
Choose a tool according to the part you are actually measuring, not just the room. A screen mesh estimate is different from a complete replacement-screen order dimension; a weatherstripping length estimate cannot choose a sealing profile.
| Your task | Start with | What the result cannot tell you |
|---|---|---|
| Replace mesh on a reusable screen frame | Screen material calculator | Whether a spline and groove combination is compatible |
| Check if a frame is approximately square | Frame diagonal calculator | Whether a twisted frame can safely be reused |
| Record a blind recess before ordering | Blind measurement helper | Model-specific factory deductions or minimum mounting depth |
| Estimate perimeter seal material | Weatherstripping length calculator | Correct bulb shape, compression range or adhesive compatibility |
| Compare several openings in one job | Printable measurement worksheet | Final product-fit approval |
Example: three windows, three different decisions
A homeowner has one screen with torn fiberglass mesh, one bent frame and one missing complete screen. First use the repair-or-replace decision guide. Estimate mesh area only for the reusable frame. Record diagonals and mounting hardware for the bent frame. For the missing screen, the measurement path assistant explains why the opening alone may not be enough to order a replacement. A calculator should not turn a measurement taken from the wrong reference into a confident purchasing instruction.
