Metric needle sizing
Clearly marked holes identify knitting needles from 2.00mm through to 12.00mm.
Needle sizer, tension ruler and magnifying gauge in one
KnitPro Needle View Sizer
Identify unmarked knitting needles, measure your tension swatch and count stitches more clearly with one compact tool. The KnitPro Needle View Sizer combines metric and US needle-sizing holes, centimetre and inch rulers, plus a transparent magnifying strip for checking stitch and row gauge.

Know your needle size before starting the next project
Needle markings can wear away, disappear inside a circular-needle join or become separated from their original packaging.
The KnitPro Needle View Sizer removes the guesswork. Slide the needle through the marked holes until you find the smallest opening through which it passes comfortably.
The matching metric and US markings let you identify the needle and translate between sizing systems without searching for a separate conversion chart.
Once the needle is identified, use the same tool to measure the finished fabric, check a tension swatch and count stitches or rows through the magnified viewing strip.
More useful than a basic needle-sizing card
US size conversion
Corresponding US sizes are printed beside the metric measurements for easy pattern conversion.
Centimetre ruler
Measure swatches, project sections and row height using the metric scale.
Inch ruler
Check patterns written around four-inch tension measurements or imperial dimensions.
Magnifying strip
The clear viewing section enlarges stitches and rows to make counting easier.
Gauge measurement
Compare your stitch and row count with the tension stated in the pattern.
Sturdy plastic body
Lightweight enough for a project bag while providing a firm measuring edge.
Compact rectangular shape
Slides neatly into a knitting notions pouch, needle case or project organiser.
Simple, accurate needle identification
How to measure an unmarked knitting needle
Begin with a hole that appears slightly larger than the needle shaft and gently insert the needle.
Move down through progressively smaller holes until the needle no longer passes freely.
The correct size is the smallest hole the main needle shaft passes through comfortably without being forced.
- Measure the straight shaft
- Do not measure the tapered point
- Do not force the needle
- Check both tips if uncertain
- Read metric or US sizing
- Record the result with your project

US knitting-needle numbering is not a perfectly linear conversion system. Use the size printed beside each hole rather than estimating from the number alone.
10cm
The standard gauge reference used by many patterns
Measure stitches and rows across the centre of a properly prepared tension swatch.
Check tension before committing to the project
Measure stitch and row gauge
Place the ruler across the centre of a relaxed, blocked swatch and count how many complete stitches sit within 10cm or four inches.
Turn the tool if necessary to measure vertically and count the number of rows across the same distance.
Compare both results with the tension stated in your pattern before beginning the full garment or fitted project.
A small difference can become a large sizing problem
Knitting one additional stitch per 10cm may appear minor, but that difference repeats across the full width of a garment.
Incorrect tension can make a jumper too narrow, a hat too loose, sleeves too long or a project require more yarn than the pattern allows.
Checking gauge before beginning is especially important for garments, fitted accessories, colourwork, yarn substitutions and projects using an unfamiliar needle material.
- Garment fit
- Finished dimensions
- Required yarn quantity
- Fabric drape
- Stitch definition
- Pattern proportion
Built-in transparent magnifying strip
Position the clear raised section over the knitting so the stitches or rows sit beneath the magnified viewing area.
The strip enlarges the fabric slightly, helping distinguish individual stitch columns and horizontal rows.
It can be particularly useful with fine yarn, dark shades, textured stitches or patterns where the stitch structure is difficult to see.
- Fine knitting yarn
- Dark-coloured projects
- Small stitch structures
- Row counting
- Tension swatches
- Small pattern text
Measure more than the initial tension square
The ruler can remain in your project bag and be used whenever the pattern asks you to continue until the work reaches a stated length.
Check cuffs, ribbing, hat depth, sleeve length, garment sections and knitted accessories without carrying a separate tape measure for every small measurement.
The rigid edge is especially convenient for measuring short sections that may curve or distort beneath a flexible tape.

Tips for an accurate tension measurement
Make the swatch larger than the required 10cm or four-inch measurement so the edge stitches do not distort the result.
Use the same yarn, needle material and stitch pattern specified for the finished project.
Wash and block the swatch in the same way the final project will be treated, then allow it to dry before measuring.
Measure in more than one place and use the centre of the swatch rather than the cast-on, cast-off or side edges.

KnitPro Needle View Sizer FAQ
What does the KnitPro Needle View Sizer do?
It identifies knitting-needle sizes, measures stitches and rows, checks tension swatches and provides metric and imperial ruler markings.
What needle sizes can it measure?
It measures round knitting needles from 2.00mm to 12.00mm, equivalent to US sizes 0 through 17.
How do I use the sizing holes?
Pass the straight needle shaft through the holes. The correct size is the smallest marked opening through which the shaft passes comfortably without being forced.
Should I measure the needle point?
No. Measure the full-diameter shaft rather than the tapered point.
Does it show metric and US sizes?
Yes. Both measurements are printed beside the sizing holes.
Can it measure circular knitting needles?
Yes. Insert the full-width part of the circular needle tip through the appropriate hole.
Can it measure interchangeable needle tips?
Yes. It is useful when interchangeable tips have been removed from their labelled case or the printed size is difficult to read.
Can it measure double-pointed needles?
Yes. Measure the straight central shaft of the double-pointed needle.
Can it measure square or cubic needles?
The holes are designed around round needle diameters. Square or cubic needles may not correspond accurately and should be checked using their original markings or packaging.
Can I use it for crochet hooks?
It may help with selected round crochet-hook shafts, but it is primarily designed as a knitting-needle sizer. Ergonomic, flattened or shaped hooks may not pass through the holes correctly.
Does it include a ruler?
Yes. It has centimetre and inch scales for measuring gauge, rows and shorter project sections.
What is the transparent strip for?
It slightly magnifies the fabric beneath it, making individual stitches and rows easier to see and count.
How do I measure knitting gauge?
Place the ruler across the centre of a relaxed and blocked swatch, then count the complete stitches across 10cm or four inches. Turn the gauge vertically to count rows.
Should I block my swatch before measuring?
Yes, particularly for garments and fitted projects. Treat the swatch as the completed item will be treated, allow it to dry and then measure.
What should I do if I have too many stitches?
Your stitches are generally too small. Try a larger needle and make a new swatch.
What should I do if I have too few stitches?
Your stitches are generally too large. Try a smaller needle and make another swatch.
Is it suitable for beginner knitters?
Yes. It makes needle identification and tension measurement easier to understand and is useful from the first project onward.
Does it cut yarn?
No. This rectangular Needle View Sizer does not include a yarn cutter.
Are knitting needles included?
No. The listing is for one KnitPro Needle View Sizer only.
Will the printed markings last forever?
Store the gauge carefully and avoid abrasive cleaning products, sharp tools and prolonged high heat to help protect the printed scales.
How should I clean it?
Wipe it gently with a soft, slightly damp cloth and dry it immediately. Avoid solvents and abrasive cleaners.
