Printable ruler, actual size

1. At the top of this page, choose a Template. The ruler pack has inch, cm and dual-edge rulers on one sheet.
2. Choose your Paper: Letter in the US and Canada, A4 almost everywhere else. The preview updates instantly.
3. Press Print. In the print window, set Scale to 100% (or Actual size) and turn off "Fit to page".
4. Cut along the solid outer lines with scissors or, for a cleaner edge, a craft knife and a straight edge.

1. Find the Scale check bars at the bottom of the sheet (on the ruler pack they are in the right column).
2. Measure the 5 cm bar with any real ruler, or lay a bank card on the card outline. It should cover it exactly.
3. If the bar is short (for example 4.8 cm), the printer shrank the page. Print again at 100% scale. See how to print at actual size for every browser.

1. Open the 12-inch ruler or 30 cm ruler and print it.
2. Cut out both pieces. Piece 2 has a grey glue tab on its left end.
3. Slide the tab under the end of piece 1 so the edges meet and the marks continue evenly (6 follows 6, or 15 follows 15).
4. Tape or glue the joint. For a one-piece ruler, choose Legal or A3 paper on the ruler pack.

1. Open the online ruler and set browser zoom to 100% (Ctrl/Cmd + 0).
2. Calibrate once: hold a bank card against the screen and drag the slider until the blue card matches it. Press Save calibration.
3. Hold the object against the screen at A (the blue marker), then tap or drag to place B (the red marker) at its other end. Read the distance below.
4. On a phone, switch to Vertical for more length. For long objects, measure in parts and press Add A–B to total after each part.

1. Open the ring sizer, print it at 100% and check the scale bars.
2. Finger strip: cut it out and wrap it around the base of your finger so the numbered end overlaps START. The US size that lines up with START is your size.
3. Ring circles: put a ring you own on the circles. The right size is the circle that just shows along the ring's inside edge.
4. Between two sizes? Choose the larger one, and measure at the end of the day when fingers are biggest.

1. Open the bracelet sizer and print it.
2. Cut out the long strip and wrap it just below your wrist bone, so the numbered end overlaps START.
3. Read your wrist size at START, then add 1.3 cm (snug), 2 cm (comfort) or 2.5 cm (loose) using the chart on the sheet.

1. Open the PD ruler, print it and cut out one ruler.
2. Stand 20 cm (8 in) from a mirror. Hold the ruler under your eyes with the marks at the top.
3. Close your right eye and put 0 under the centre of your left pupil. Then close your left eye, open your right, and read the mark under your right pupil. That number is your PD in mm.
4. Repeat three times and use the average.

1. Print the protractor and cut along its outline. Card stock works best.
2. Put the centre cross on the corner of the angle and line up the baseline with one arm.
3. Read where the other arm crosses the scale. Use the row of numbers that starts at 0 on the arm you lined up.

1. Print the tape measure and cut out every strip with its glue tab.
2. Glue each strip's tab under the end of the previous strip so the numbers continue.
3. Wrap it around your waist, chest, hips or head. Keep it level and snug, and read inches on one edge or cm on the other.

1. Open graph paper and choose the 1 mm or 1/4 inch template.
2. Print at 100%. Every square is then exactly 1 mm or 1/4 inch, so you can measure straight off the grid.

1. Open the converter and type in any box, for example 3 5/8 in the fraction box.
2. Every other unit updates instantly. Set Round fractions to to match your ruler's smallest mark (usually 1/16").

1. Open how to read a ruler and read the short guide.
2. Practise with the quiz: start at halves, then work up to sixteenths. Each answer shows how it was worked out.

1. Open the online protractor.
2. To measure something in a picture, press Open photo. The photo stays on your device and is never uploaded.
3. Drag the dark middle handle onto the corner, then drag the blue and red handles along each side. The angle updates as you drag.
4. Tick Reflex angle for angles over 180°. The readout also shows how far each arm is from horizontal, which is handy for slopes and roof pitch.

1. Open the online measuring tape and calibrate once with a bank card.
2. Measure the first part from A to B and press Add A–B to total.
3. Slide the object so the point you reached sits at A, measure the next part and add it. Repeat until you reach the end, then read the total.
