Press (or click) ESC to abort drawing the current line or clear all measurements. If you need a real ruler or tape, you can print a ruler, or purchase online.Use the measurements table to remove any measurement.Hit (or click) DEL to remove the last measurement.( Bug: Saved with the current resolution, not the original. Save the annotated image and the measurement data via the respective buttons or right-click the image and "Save Image As.Create measurement lines (green) by click-and-dragging (remove them by clicking on the 'remove' link in the measurement table below).Enter the real-world length of the first dimension as reference - the other measurements will be scaled accordingly.Create the reference dimension (red) by click-and-dragging the first measurement line onto an object with known size.Rotate the image as needed ( Limitation: measurement lines can't be rotated with the image). ![]() Expand the editor area for a larger view.The picture will be scaled to fit the page width. or drag&drop an image anywhere onto this page.your kitchen furniture don't fit - No Warranty Detailed instructions The accuracy depends very much on the image. close-by and at the same distance from the camera.Īdditionally, camera lenses cause distortions (think fish-eye view).Īs a result, expect this method to be useful only for estimates. Without additional information, it cannot be determined whether it is a small object nearby or a large one far away (depth perception is more difficult with one eye closed).Ĭonsequently, to determine the size of an object from a single image, a reference object for scale needs to be in the same image plane, i.e. Photos on the other hand are a two-dimensional projection (image) of the three-dimensional world (object).Īs a result, objects appear smaller with increasing distance - that's called perspective. The real-world dimensions are then obtained by simply applying the scale. If you are interested to help this, please visit this translation page.It's simple to determine distances on maps or technical drawings such as architectural (floor) plans when you have its scale and a ruler.īecause everything is in a single plane, measurements can be taken directly. We are looking for volunteer to improve the content in your native language, We hope to provide a more user-friendly experience,Īre you willing to offer a native language version for your country ? I know many people prefer use their native language, The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. ![]() For example, a scale of 1:5 means 1 on the map represents the size of 5 in the real world. It is used in maps to represent the actual figures in smaller units. Scale is the ratio that defines the relation between the actual figure and its model. In math, the term scale is used to represent the relationship between a measurement on a model and the corresponding measurement on the actual object. It helps us calculate the scale ratio more easily. How adjusting this virtual ruler to actual size You can adjust the size in two ways: The first: To adjust the size of the ruler by select the size of your monitor. If you want to know the scale factor(ratio) between two lengths, Also See: Online Ruler(MM,CM,INCH) MM(CM) Ruler Inch Ruler 1/8 Inches Ruler 1/16 Inches Ruler 1/32 Inches Ruler MM to Inches. On the building plan the width of the front door is 18.6 mm.įirst, we convert the unit from millimeter to centimeter. Then divide the scale factor of scale length, for example Use real length multiply the scale factor of it,
