This 25w bulb is 638mm long excluding pins and 650mm long including pins. The manufacturer specifies a tolerance of +/- 3mm for these tubes.
Please note: When buying T4 lamps, it is important to purchase lamps from the same manufacturer as the light fitting that you have or at least check the size very carefully. T4 lamps vary between manufacturers in tube length and cap style, so are unlikely to fit other manufacturers fittings.
T4 fluorescent fittings have been discontinued since 2015 due to EU regulations. The electronics are located in the light fitting and not the tube. If you are finding your lamps are not lasting as long as expected, this would indicate a fault in the light fitting and not the tube - unless the tube is physically smashed it's very unlikely to have a fault. You can test tubes and fittings by swapping tube from another working fitting. Unfortunately manufacturers no longer provide a guarantee for T4 tubes, as the light fittings they are installed into may be approaching the end of their life.
