NOTE 1: 85th percentile speed measurement is dealt with in TA 22 / 81 "Vehicle speed measurement on all-purpose roads" in Volume 5 of the Design Manual for Roads and Bridges (see para 1.3). The right hand column (over 60 mph) applies generally to all-purpose dual carriageway roads and, where appropriate, to motorways. It should be noted that other factors such as carriageway width and the complexity of the background against which the sign is placed may also affect sign size (see notes 2 and 3 below).

NOTE 2: The smaller bracketed sign sizes should be used only where special amenity considerations or physical constraints apply. It should be borne in mind that smaller signs are likely to be seen later, and do not become legible until drivers are closer to them, with less time to react.

NOTE 3: The larger bracketed sign sizes should be used where site conditions require increased conspicuity, such as on a wide road or where the accident record calls for greater emphasis. Conspicuity can also be increased by the use of yellow backing boards (see paras 1.31 to 1.33).

NOTE 4: The size of a sign and its corresponding supplementary plate should be taken from the same column. Where two sizes are shown for both the sign and the plate, corresponding sizes (smaller or larger) should be used.

NOTE 5: Smaller sizes, for use in bollards and alongside traffic signals, are not shown in the table.

NOTE 6: Smaller sizes, for use in bollards, are not shown in the table.

NOTE 7: This sign is normally used only where the speed limit is 30 mph or less (see para 4.22).

NOTE 8: The sizes of signs to diagrams 622.5, 622.6, 625.1, 810 and 951 are related to site conditions and not to the speed of traffic. Generally, the unbracketed size shown alongside the diagram should be used. The smaller sizes shown for diagrams 625.1 and 951 are used where the signs are mounted on, or in, bollards. The smaller size for diagrams 622.5 and 622.6 may be appropriate where amenity considerations or physical constraints apply. The larger sizes for diagrams 810 and 951 should be used where there is a need to increase conspicuity, or, in the case of diagram 810, where the sign is mounted on the opposite side of the road.

NOTE 9: These signs have a range of x-heights shown as minimum and maximum. The sizes shown in the table are those appropriate for a particular traffic speed. However, intermediate sizes may be used, especially where the traffic speed is in the middle of the range for a specific column (e.g. where the 85th percentile speed is 35 mph, the x-height of the sign to diagram 818.2 could be 110 mm). The maximum x-height of 250 mm for the sign to diagram 878 is not shown as this size is unlikely to be used, but might be considered for motorways with four or more lanes.

NOTE 10: The smallest size (20 mm x-height) is likely to be appropriate when the sign faces the footway (see para 6.16).

NOTE 11: Where the "no entry" sign to diagram 616 is used with a supplementary plate to diagram 954 or 954.2, see para 15.22. Where the “no entry” sign is used in connection with a contra-flow cycle lane, see para 17.19.

NOTE 12: Where the sign to diagram 619 is used in connection with an advisory contra-flow cycle lane, see para 17.27.

NOTE 13: Where an "Except local buses" supplementary plate is required with a 1200 mm diameter sign to diagram 952, this should be a variant of diagram 620, with an x-height of 125 mm.

NOTE 14: The table below shows the appropriate x-height of diagram 954.4 when used with the "no through road" sign to diagram 816.

x-height of diagram 954.4 (mm)	Height of diagram 816 (mm)
400	37.5
480	50
560	62.5
