These are the characters that will be measured. Choose from the standard ranges, or input your own ranges or single character codes. Codes are accepted in decimal or hexadecimal, e.g. 256 or 0x0100 or U+0100 or \u0100. Use "-" or ".." between codes to define a range.
256
0x0100
U+0100
\u0100
These will be measured in pairs to determine which pairs of characters are smaller than the sum of their individual widths.
Type the font name in the box. Common font names will be auto-completed. The "measure size" is the font size used for measuring the characters, and also affects the size of the SVG measurement area below.
Press this button to start measuring the characters and kerning pairs. The results will appear below the SVG measurement area.
The area below is an SVG document where the characters and pairs are measured.
Enter a string in the box below and choose the font size to test the measurement algorithm. The text and a bounding box will be drawn in the SVG measurement area above - the bounding box is calculated using the algorithm.
These results show the calculated and actual string widths, along with the pre-metrics method calculation using both the font adjust value above and the adjust value determined from the mean character width.
These are the measured metrics. The height, baseline and mean width are used by the new algorithm to calculate the position and size of strings. The calculated adjust value is not used by the new algorithm, but it can be used for SVGGraph font adjust options (using the old algorithm) instead of the metric file.
